Abstract:
Polycrystalline silicon (poly-Si) thin films were obtained by aluminium induced crystallisation of amorphous silicon suboxide (a-SiOx, x = 0.22) via annealing of a-SiO0.22/Al bilayer structures at 550 °C for 4 - 30 h. The a-SiO0.22/Al thickness ratio was approximately 1. According optical microscopy measurements, the crystallized fraction reached the saturation value of 85% after annealing for 20 h. The further increase in the annealing time didn’t lead to an increase in this value. X-ray diffraction measurements revealed that the formed poly-Si had a strong Si (111) preferred orientation.

Abstract:
ABSTRACTWe report formation of thin aluminum oxide AlOx films on the silicon surface by a simple method of Al metal evaporation in oxygen gas atmosphere. 520 μm thick 30-Ωcm p-type-silicon substrates with a top bare surface and a rear surface coated with 100 nm thick thermally grown SiO2 layers were prepared. AlOx films were formed on the top surfaces by Al metal evaporation up to 20 s in oxygen gas atmosphere at 0.8 Pa with a flow rate of 3 sccm. Samples were subsequently annealed with 9.0x105 Pa H2O vapor at 260°C for 3 h. Measurement of capacitance response to a modulation voltage at 500 kHz as a function of bias gate voltages C-V revealed that AlOx films had the effective oxide thickness ranging from 2.0 and 2.6 nm were formed. C-V measurements also revealed that negative fixed charges were accumulated with a density of 5x1012 cm-2 in AlOx films. Photo-induced carrier microwave absorption measurement resulted in a high minority carrier effective lifetime τeff of 3.6x10-4 s comparable to that of 4.1x10-4 s for thermally grown SiO2 passivation. Field effect passivation was probably caused by negative charges in AlOx so that the surface recombination velocity decreased to 70 cm/s. X-ray reflectivity analysis indicated that the interfacial layer like SiOx was formed between AlOx and Si substrate. High pressure H2O vapor heat annealing caused increase in the density and decrease in the thickness of AlOx layers, although it increased the density and thickness of the interfacial SiOx layer thickness. H2O vapor treatment is effective to improve the quality of nanometer thick AlOxlayer.

Abstract:
Electrocatalysts are essential components in many emerging electrochemical technologies due to their ability to efficiently facilitate the interconversion between electrical and chemical energy. However, significant improvements in the stability, activity, and selectivity of state-of-the-art electrocatalysts must be made if these technologies are going to play a major role in a sustainable energy future. The vast majority of electrocatalysts used in today’s commercial devices are comprised of metallic nanoparticles or thin films that are deposited onto a conductive support and partially exposed to the bulk electrolyte. By contrast, this work has explored an alternate electrocatalyst architecture in which the active electrocatalyst has been encapsulated by an ultrathin permeable overlayer. Specifically, we encapsulate Pt nanoparticle and thin film electrocatalysts with 2-20 nm thick layers of silicon oxide (SiOx) fabricated using a room temperature deposition process.[1] Through a combination of physical characterization and electroanalytical measurements, we show that these permeable overlayers can serve as nano-scale membranes that provide significant benefits for stabilizing Pt nanoparticles and imparting advanced catalytic functionalities such as poison-resistance. This work has focused on SiOx-encapsulated Pt thin films electrocatalysts for the hydrogen evolution reaction, but the membrane coated electrocatalyst architecture also has great potential as a tunable platform that can be extended to many other materials and chemistries.

Abstract:
The stability/instability behavior of polystyrene (PS) films with tunable thickness ranging from higher as-cast to lower residual made on Si substrates with and without native oxide layer was studied in this paper. For further extraction of residual PS thin film (hresi) and to investigate the polymer–substrate interaction, Guiselin’s method was used by decomposing the polymer thin films in different solvents. The solvents for removing loosely adsorbed chains and extracting the strongly adsorbed irreversible chains were selected based on their relative desorption energy difference with polymer. The PS thin films rinsed in chloroform with higher polarity than that of toluene showed a higher decrease in the residual film thickness but exhibited earlier growth of holes and dewetting in the film. The un-annealed samples with a higher oxide film thickness showed a higher decrease in the PS residual film thickness. The effective viscosity of PS thin films spin-coated on H-Si substrates increased because of more resistance to flow dynamics due to the stronger polymer–substrate interaction as compared to that of Si-SiOx substrates. By decreasing the film thickness, the overall effective mobility of the film increased and led to the decrease in the effective viscosity, with matching results of the film morphology from atomic force microscopy (AFM). The polymer film maintained low viscosity until a certain period of time, whereupon further annealing occurred, and the formation of holes in the film grew, which ultimately dewetted the film. The residual film decrement, growth of holes in the film, and dewetting of the polymer-confined thin film showed dependence on the effective viscosity, the strength of solvent used, and various involved interactions on the surface of substrates.

Abstract:
Deep-ultraviolet (DUV) light-transparent conductive composite thin films, consisting of dispersed multiwalled carbon nanotubes (MWCNTs) and SiO2 matrix composites, were fabricated on a quartz glass substrate. Transparent and well-adhered amorphous thin films, with a thickness of 220 nm, were obtained by weak ultraviolet (UV) irradiation (4 mW cm−2 at 254 nm) for more than 6 h at 20−40 °C onto the precursor films, which were obtained by spin coating with a mixed solution of MWCNT in water and Si(IV) complex in ethanol. The electrical resistivity of MWCNT/SiO2 composite thin film is 0.7 Ω·cm, and transmittance in the wavelength region from DUV to visible light is higher than 80%. The MWCNT/SiO2 composite thin film showed scratch resistance at pencil hardness of 8H. Importantly, the resistivity of the MWCNT/SiO2 composite thin film was maintained at the original level even after heat treatment at 500 °C for 1 h. It was observed that the heat treatment of the composite thin film improved durability against both aqueous solutions involving a strong acid (HCl) and a strong base (NaOH).

Abstract:
There has been a rapidly increasing interest in the synthesis and characterization of Si- nanostructures embedded in a dielectric matrix, as it can lead to energy-efficient and cost-effective Complementary Metal-Oxide-Semiconductor (CMOS)-compatible Si-based light sources for optoelectronic integration. In the present contribution, first an overview of the SiOx as a dielectric matrix and its limitations are discussed. We then review the literature on hydrogenated amorphous silicon nitride (a-SiNx:H) as a dielectric matrix for Si-nanostructures, which have been carried out using silane (SiH4) and ammonia (NH3) as the reactant gases. Our studies demonstrate that the least amount of hydrogen in the as-deposited (ASD) a-SiNx:H films not only allows in-situ formation of Si-nanostructures but also stabilizes silicon nitride (Si3N4) phase. The recent advances made in controlling the shape and size of Si-nanostructures embedded in a-SiNx:H matrix by swift heavy ion (SHI) irradiation are briefly discussed.

Abstract:
Nanocrystalline silicon embedded in silicon oxide (nc- Si/SiO2 ) films have been in situ grown at a low substrate temperature of 300°C by reactive magnetron co-sputtering of Si and SiO2 targets in a mixed Ar/H2 discharge. The influences of H2 flow rate (F H ) on the microstructural properties of the deposited nc- Si/SiO2 films were investigated. The results of XRD and the deposition rate of nc- Si/SiO2 films show that the introduction of H2 contributes to the growth of nc- Si grains in silicon oxide matrix. With further increasing F H , the average size of nc- Si grains increases and the deposition rate of nc- Si/SiO2 films decreases gradually. Fourier transform infrared spectra analyses reveal that introduction of hydrogen contributes to the phase separation of nc- Si and SiO x in the deposited films. Moreover, the Si–O 4-n Si n(n = 0, 1) concentration of the deposited nc- Si/SiO2 films reduces with the increase of F H , while that of Si – O 4-n Si n(n = 2, 3) concentration increases. These results can be explained by that active hydrogen atoms increase the probability of reducing oxygen from precursor in the plasma and prompting oxygen desorption from the growing surface. This low-temperature procedure for preparing nc- Si/SiO2 films opens up the possibility of fabricating the silicon-based thin-film solar cells onto low-cost glass substrates using nc- Si/SiO2 films.

Solar cells have become an increasingly viable alternative to traditional, pollution causing power generation methods. Although crystalline silicon (c-Si) modules make up most of the market, thin films such as hydrogenated amorphous silicon (a-Si:H) are attractive for use in solar cell modules because of the capacity to fabricate cells with much less material. However, several challenges exist in making this material a more practical alternative to c-Si; despite having superior optical absorption properties, a-Si:H suffers in electronic transport, having a hole mobility 3-7 orders of magnitude less than that of c-Si. In the MOSFET transistor industry, carrier speeds and thus mobilities of c-Si were improved through the application of stress in the material. This work hypothesizes that a similar application of stress on a-Si:H thin films can enhance this material's hole mobility. A comprehensive study of the parameter space for a plasma enhanced chemical vapor deposition technique used to produce a-Si:H is performed. This enables the control of stress within the deposited film, from compressive to tensile; the mechanical limits of the material resulting in buckling and delamination failure are observed. Further characterization of a-Si:H thin films with different levels of engineered stress was performed; an analysis of the films' surface using AFM measurements to calculate a fractal dimension for each did not result in a significant descriptor of the surfaces' domain distribution. This work includes a detailed analysis of the theory of time-of-flight for measuring carrier mobility in thin film materials, and the system requirements needed to perform them.

Magister Scientiae - MSc (Physics)
An increasing energy demand and growing environmental concerns regarding the use of fossil fuels in South Africa has led to the challenge to explore cheap, alternative sources of energy. The generation of electricity from Photovoltaic (PV) devices such as solar cells is currently seen as a viable alternative source of clean energy. As such, crystalline, amorphous and nanocrystalline silicon thin films are expected to play increasingly important roles as economically viable materials for PV development. Despite the growing interest shown in these materials, challenges such as the partial understanding of standardized measurement protocols, and the relationship between the structure and optoelectronic properties still need to be overcome.

The kinetics of silicon etching by atomic hydrogen is monitored in situ by UV - visble ellipsometry .Several plasma parameters (temperature, RF power, H2 gas pressure, the doping of the material) that may impact the kinetics were probed. An analysis of the spectroscopic ellipsometry spectra, thanks to an appropriate optical model, allowed evidencing their effects on the time constant, the thickness and the hydrogen excess of the H-modified layer.The same hydrogen plasma treatment repeated on i/p and i/n H base junctions revealed a particular behavior of the etching kinetics in the junction zone.

Abstract:
When Candyman was released in 1992, Roger Ebert gave it his thumbs up, remarking that the film was “scaring him with ideas and gore, rather than just gore.” Indeed, Candyman is almost unique in 1990s horror cinema in that it tackles its sociopolitical themes head on. As critic Kirsten Moana Thompson has remarked, Candyman is “the return of the repressed as national allegory”: the film's hook-handed killer of urban legend embodies a history of racism, miscegenation, lynching, and slavery, “the taboo secrets of America's past and present.” This book considers how Candyman might be read both as a “return of the repressed” during the George H. W. Bush era, and as an example of 1990s neoconservative horror. It traces the project's development from its origins as a Clive Barker short story (The Forbidden); discusses the importance of its gritty real-life Cabrini-Green setting; and analyzes the film's appropriation (and interrogation) of urban myth. The two official sequels (Candyman: Farewell to the Flesh [1995] and Candyman: Day of the Dead [1999]) are also considered, plus a number of other urban myth-inspired horror movies such as Bloody Mary (2006) and films in the Urban Legend franchise. The book features an in-depth interview with Candyman's writer-director Bernard Rose.

Abstract:
This chapter explores the contacts and conflict between novelistic point of view and the practice of cinematic spectatorship. It focuses on H. D.’s singular contributions to the film journal Close Up (1927–1933). This film criticism was an important context for developing the forms of prose experimentation that would occupy her during the early 1930s. In detaching vision from a presumed subject, H. D. found that film asks its viewers not only to see but to translate encrypted “abstract . . . remote . . . symbolical” meanings from the “raw-picked” images that pass across the screen. This literary appropriation of spectatorship would come to structure her contemporaneous work, The Usual Star. This novel exemplifies the formal ambition of H. D.’s prose innovations, suggesting an alternate history of the modernist novel in which the totemic value of point of view had been dislodged.

Abstract:
This book is the first to provide a reading of the recent ‘Weird’ or ‘New Wave’ of Greek cinema, both through the concept of biopolitics and in the context of contemporary World Cinema politics, aesthetics, as well as production and circulation strategies. Its main aim is to show the ways in which, since the beginning of the 21st century, cinema and other cultural forms in Greece have responded to a sense of Crisis and an ever expansive management of life that we have now come to call biopolitics. Through close cultural and film analysis, the Greek Weird Wave is proposed as a paradigmatic cinema of biopolitical realism, a trend observable more widely in world cinema today. Key films such as Yorgos Lantimos’s Dogtooth, Alps and The Lobster, Athina Rachel Tsangari’s Attenberg, Syllas Tzoumerkas’s Homeland, Alexandros Avranas’s Miss Violence and Panos H. Koutras’s Strella, are read together with less well-known short, medium and feature-length films by directors such as Konstantina Kotzamani, Yorgos Zois, Vassilis Kekatos, Alexandros Voulgaris, Argyris Papadimitropoulos, Babis Makridis. At the same time, the book offers an analysis of the larger cultural context of 21st-century Greece, often explaining the films’ major thematic and formal choices through references to contemporary novels, theatre performances, activist texts and political events.

Abstract:
The Novel After Film examines how literary fiction has been redefined in response to the emergence of narrative film. It charts the institutional, stylistic, and conceptual relays that linked literary and cinematic cultures, and that fundamentally changed the nature and status of storytelling in the early twentieth century. In the cinema, a generation of modernist writers found a medium whose bad form was also laced with the glamour of the popular, and whose unfamiliar visual language seemed to harbor a future for innovative writing after modernism. As The Novel After Film demonstrates, this fascination with film was played out against the backdrop of a growing discourse about the novel’s respectability. As the modern novel was increasingly venerated as a genre of aesthetic refinement and high moral purpose, a range of authors, from Virginia Woolf and H. D. to Henry Green and Aldous Huxley, turned their attention to the cinema in search of alternative aesthetic histories. For authors working in modernism’s atmosphere of heightened formal sophistication, film’s violations of style took on a perverse attraction. In this way, film played a key role in changing the way that novelists addressed a transforming public culture which could seem at moments to be leaving the novel behind.

Full text
Abstract:
In Indirect Subjects, Matthew H. Brown analyzes the content of the prolific Nigerian film industry's mostly direct-to-video movies alongside local practices of production and circulation to show how screen media play spatial roles in global power relations. Scrutinizing the deep structural and aesthetic relationship between Nollywood, as the industry is known, and Nigerian state television, Brown tracks how several Nollywood films, in ways similar to both state television programs and colonial cinema productions, invite local spectators to experience liberal capitalism not only as a form of exploitation but as a set of expectations about the future. This mode of address, which Brown refers to as “periliberalism,” sustains global power imbalances by locating viewers within liberalism but distancing them from its processes and benefits. Locating the wellspring of this hypocrisy in the British Empire's practice of indirect rule, Brown contends that culture industries like Nollywood can sustain capitalism by isolating ordinary African people, whose labor and consumption fuel it, from its exclusive privileges.

Abstract:
This chapter presents a general theory of color perception that focuses on something close to what Wilfred Sellars called “the sensory core”, something well-described in a passage from H. H. Price’s Perception. It develops the implications of that theory for (i) the distinctive epistemology of perception, which in the best case involves something better than mere knowledge, (ii) the nature of ganzfelds, film color, highlights, lightened and darkened color, auras, after-images, color hallucinations and the like, (iii) the account of when things are predicatively colored, and (iv) the nature of the category of quality. The chapter argues that as a consequence of understanding the sensory core we should reject the two most influential views in the philosophical theory of perception. Our most basic perceptual experiences are not adequately modeled as attitudes directed upon propositions. Nor are they adequately modeled as directed upon facts, understood as items in our perceived environment.

Abstract:
Released in 1932, The Mummy moved Universal horror away from the Gothic Europe of Dracula and Frankenstein and into a land of deserts, pyramids, and long-lost tombs. In doing so, the film continued a tradition of horror fiction that is almost as old as the Western pursuit of Egyptology, as numerous European and American authors from the nineteenth and early twentieth centuries had portrayed Egypt as a place of mystery and magic. This book examines the roots of The Mummy. It shows how the film shares many of its motifs with the work of writers such as Bram Stoker, Arthur Conan Doyle, and H. Rider Haggard, whose tales of living mummies, immortal sorcerers, and Egyptian mysticism bear strong resemblances to Universal's movie. In addition, the book discusses how The Mummy drew upon a contemporary vogue for all things ancient Egyptian: the tomb of Tutankhamun was discovered the decade before the film was released, prompting sensationalistic rumours of a curse. This is the story of what happened when Hollywood horror went to Egypt.

Abstract:
Somewhat overlooked upon its initial release in 1995, John Carpenter's In the Mouth of Madness has since developed a healthy cult reputation. But far more than simply a fan favourite, this closing instalment of the acclaimed director's self-described “apocalypse trilogy” (following The Thing and Prince Of Darkness) stands today as one of his most thematically complex and stylistically audacious pieces of work. The story of an insurance investigator drawn into the supposedly fictional universe of a best-selling horror novelist, the film is an extension of many recurring themes found in Carpenter's filmography (the end of the world, the loss of free will, a distrust of mass industry and global corporations, the cataclysmic resurgence of ancient evil), as well as an affectionate homage to the works of H. P. Lovecraft (and horror literature more broadly) and a self-reflexive celebration of the horror genre that predates the Scream-inspired postmodernist boom of late-nineties genre cinema. While numerous books and countless academic essays have been written about Carpenter's work, surprisingly little has focused exclusively on In the Mouth of Madness, a film which feels more prescient, more essential, and more daringly complex than ever. This book seeks to redress this imbalance, at last positioning this overlooked masterpiece as essential Carpenter.

Abstract:
Population growth and urbanization have led to water scarcity and pollution, which is a health hazard not only to humans but also to the ecosystem in general. This has necessitated coming up with ways of treating water before consumption. Photocatalysis has proved to be one of the most promising cheap techniques that involve chemical utilization of solar energy. TiO2 widely used in photocatalysis absorbs a narrow range of the solar spectrum compared to ZnO. In this regard, this study aimed at preparing and optimizing cobalt-pigmented ZnO, which is applicable in photocatalytic water treatment. The objectives in this study were to fabricate zinc oxide (ZnO) thin films by anodization, pigment the fabricated films with varying cobalt concentrations, characterize the fabricated films optically, and investigate the cobalt-pigmented ZnO’s performance in the methylene blue degradation under UV light irradiation. Mirror-polished zinc plates were sonicated in ethanol and rinsed. Anodization was done at room temperature in 0.5 M oxalic acid at a constant voltage of 10 V for 60 min, and cobalt electrodeposited in the films. Post-deposition treatment was done at 250°C. Optical properties of the films were studied using a UV-VIS- NIR spectrophotometer in the solar range of 300–2500 nm. The photocatalytic activity of the fabricated films was studied in methylene blue solution degradation in the presence of UV light irradiation for 5 h. Cobalt pigmenting was observed to reduce reflectance and optical band gap from 3.34 to 3.10 eV indicating good photocatalytic properties. In this study, ZnO film pigmented with cobalt for 20 s was found to be the most photocatalytic with a rate constant of 0.0317 h−1 and hence had the optimum cobalt concentration for photocatalytic water treatment. This can be applied in small-scale water purification.

Abstract:
BaF2 thin films of thickness 20 nm are prepared using the electron beam evaporation technique (at room temperature) on glass, silicon (Si) as well as aluminum (Al) substrate, respectively. These substrates play a crucial role in the evolution of thin film surface morphology. The thin films grown far from equilibrium have self-affine nature which is reminiscent of fractal behaviour. The surface morphology of films is recorded by atomic force microscopy (AFM). Scaling law analysis is performed on AFM images to confirm that the thin film surfaces under investigation have self-affine nature. The concept of fractal geometry is applied to explore-how different substrates affect the surface morphology of films. The fractal dimension of horizontal as well as vertical sections of AFM images are extracted by applying Higuchi’s algorithm. Value of Hurst exponent (H) for each sample is estimated from fractal dimension. It is found to be greater than 0.5 for Al as well as glass substrates, indicating that the height fluctuations at neighboring pixels are correlated positively. However, for Si substrate, its value is less than 0.5 which suggests that the height fluctuations at neighboring pixels are not positively correlated.

Abstract:
Abstract In 1919 H. Barkhausen discovered that the magnetization of iron is associated to a crackling noise that could be revealed as an inductionpulse in a coil. This observation provided an indirect indication of the existence of ferromagnetic domains and stimulated an intense research activity spanning eight decades. The Barkhausen effect is probably the cleanest example where the mechanism of self-organized criticality can be applied to an experiment. The scaling exponents describing Barkhausen avalanche distributions in bulk materials can be quantitatively explained by studying the depinning of domain walls. Our understanding is still not complete in the case of magnetic thin films where the domain structure and the avalanche dynamics are often quite intricate.

Abstract:
This chapter examines five film adaptations of Lawrence’s works released between 2002 and 2014. Two films (Odour of Chrysanthemums and Lady Chatterley et l'homme des bois) exemplify surface fidelity by preserving Lawrence's setting, plot, and character. The three remaining films (The Rocking Horse Winner, The Blind Man, and The White Stocking) seriously disturb the textual surface. This juxtaposition of strategies reveals that neither is superior. Both have resulted in remarkable films preserving Lawrence's substance even through the process of transformation. The contemporary Lawrence films illuminate his writing as both prophetic and cinematic. The three transformative films verify that his work anticipates the preoccupations and even the events of recent times. All five films reveal Lawrence as a cinematic writer despite his professed dislike of film. The intensely visual scenes all throughout his fiction prefigure cinematic techniques developed long after his death.

Abstract:
Recently, electrochromic thin films and thin film devices have attracted more and more interest because of strong possibility to act as smart windows and smart glass that may be widely used in the daily life[1]. The electrochromic thin film devices usually have a five layers structure: an actual electrochromic layer, an ionic conductor and an ion storage layer are sandwiched between two outer transparent electrical conductive layers, WO3 film is used as the actual electrochromic films in the general studies. The coloration and bleaching are accomplished when positive ions (Li+, H+ etc. )are moved from the ion storage, via the ionic conductor, into the electrochromic layer, or in the inverse direction. Currently, the electrochromic thin films or thin film devices are characterized by electrochemical analysis and optical spectral transmittance measurement. In fact, the electrochromic effect is a spectral absorption modulation, the investigation of the optical absorption variation during the electrochromic process may offer us more information about the process.

Abstract:
Thin and very thin (less than 10 μm) liquid films driven by a forced gas/vapor flow (stratified or annular flows), i.e. shear-driven liquid films in a narrow channel is a promising candidate for the thermal management of advanced semiconductor devices in earth and space applications. Development of such technology requires significant advances in fundamental research, since the stability of joint flow of locally heated liquid film and gas is a rather complex problem. The paper focuses on the recent progress that has been achieved by the authors through conducting experiments. Experiments with water in flat channels with height of H = 1.2–2.0 mm show that a liquid film driven by the action of a gas flow is stable in a wide range of liquid/gas flow rates. Map of isothermal flow regime was plotted and the length of smooth region was measured. Even for sufficiently high gas flow rates an important thermocapillary effect on film dynamics occurs. Scenario of film rupture differs widely for different flow regimes. It is found that the critical heat flux for a shear driven film can be 10 times higher than that for a falling liquid film, and exceeds 400 W/cm2 in experiments with water for moderate liquid flow rates. This fact makes use of shear-driven liquid films promising in high heat flux chip cooling applications.

Abstract:
Heparin is an appropriate molecule to suppress the thrombus formation in the initial stages of blood contact with an artificial material. Therefore the covering of a synthetic material with heparin-like molecules is a great importance issue in biomaterial science and engineering. In order to reach this goal this paper deals with the plasma deposition of thin heparin-like films on microscope slides from RF-excited heparin/methane low pressure plasmas. Plasma were excited by a RF-power supply operating on 13.56 MHz at a fixed power of 50 W. Heparin was diluted in ethanol and fed into the plasma chamber in mixtures of 50% of CH4 (in pressure) at 10 Pa. Films molecular structure was characterized by Fourier transform infrared spectroscopy (FTIR here in). Molecular spectra presented absorption bands due C-H, O-H and C-O stretching and bending modes. Films surface wettability was investigated by contact angle measurements. The experimental results show values varying from 650 to 200. Surfaces optical microscopy showed the occurrence of heparin islands distributed almost uniformly over the _lm. The bloods coagulation time placed in contact with glass substrate covered by plasma deposited heparin/methane films was measured by thrombosis time and activated thromboplastin.

Abstract:
The purpose of this paper is to develop a direct method to measure e31 of PZT thin films regardless of the boundary conditions of the specimens. The experimental setup consists of a silicon beam with a PZT film excited by a tiny shaker. A charge amplifier detects the charge accumulated in the PZT film. A spectrum analyzer processes the charge amplifier’s output to obtain a frequency spectrum. In addition, three calibration points are defined along the PZT film as 1, 2, and 3. These points are evenly spaced with distance Δx. A laser Doppler vibrometer (LDV) measures the deflection w1, w2, and w3 of the calibration points 1, 2, and 3. According to Euler-Bernoulli beam theory, the normal strain is ε ≈ 0.5h(w1 – 2w2 + w3)/(Δx)2, where h is the thickness of the cantilever. Finally, the ratio of the charge to the strain ε gives e31. Note that this approach does not depend on the boundary conditions of the specimen. Therefore, the boundary conditions do not affect the accuracy of the measurements. To demonstrate the direct measurement method, we fabricate a silicon cantilever beam with a PZT film using sol-gel processes. The dimensions of the silicon canteliver and the PZT thin film are 30 mm × 7.5 mm × 0.4 mm and 4 mm × 4 mm × 1 μm, respectively. Using the resonance amplitude of the first bending mode at 520 Hz, we obtain e31 to be 0.24 C/m2.

Abstract:
The goal of this study is to investigate photocatalytic semiconductor systems which are layered thin film composites built from perovskite oxide materials with characteristics such as small and large band gaps and/or ferroelectricity. In order to improve the efficiency of photocatalysis, semiconductor heterojunctions within the developed composites have been designed to possess electronic band offsets favoring the separation of photo-induced electron and hole (e−/h+) pairs. Furthermore, the remanent polarization of the ferroelectric component within the composites has been utilized to induce favorable band bending at the material interface, lowering the potential barrier for electron transfer. The band offsets and ferroelectric polarization could be considered as built-in electric fields; how they interact with photo-induced e−/h+ would greatly affect the photocatalytic properties of the composites. In this study, various perovskite oxide thin film materials — large band gap strontium titanate (SrTiO3), small band gap silver niobate (AgNbO3) and ferroelectric lead lanthanum titanate (PLT) — were combined to form layered thin film composites. The composites were then adopted as photoanodes in a photoelectrochemical cell and detailed characterization of their photocurrent response was carried out under different light irradiation and ferroelectric polarization conditions. Electronic band offsets at the material interface (i.e., heterojunction) were determined by ultraviolet-visible spectrophotometry and ultraviolet photoelectron spectroscopy. Electric field poling of the ferroelectric component was achieved by non-contact corona charging. Our results have shown that the band offsets at the SrTiO3-AgNbO3 heterojunction were about 1.0 eV in conduction band edge and 0.4 eV in valence band edge, promoting the rapid separation of photo-induced charge carriers; i.e., the flow of e− from SrTiO3 to AgNbO3 and the flow of h+ from AgNbO3 to SrTiO3. It was found that ferroelectric PLT could be used as a seeding layer for the low-temperature (500 °C) growth of SrTiO3/AgNbO3 thin film composites on ITO/glass substrates, forming a layered structure of SrTiO3/AgNbO3/PLT/ITO. In addition, the photocurrent density of the composites could be increased by depositing gold nanoparticles at the PLT-ITO interface. When the polarization of the PLT layer was poled toward the AgNbO3 layer, the potential barrier associated with the flow of e− to the ITO electrode was reduced by favorable band bending created at the AgNbO3-PLT interface. This resulted in a significant increase in photocurrent density.
