Abstract:

We have investigated the growth and characteristics of nanoscaled thin films of carbon, nickel, and platinum. The nanoscaled thin films were deposited on Si and quartz substrates with or without a surface layer of carbon, nickel, or platinum using a DC magnetron sputter deposition technique. The thicknesses, which were determined using ellipsometry, are all less than 10 nm. The film structures were examined using glazing angle incident x-ray diffractometry and Raman spectroscopy. The electrical and optical properties were determined using a four point probe technique and UV-VIS-IR spectrometry, respectively.

Abstract:

Nanoscaled gallium-doped ZnO (GZO) thin films, bi-layer Pt/GZO thin films, and tri-layer GZO/Pt/GZO thin films were prepared and their characteristics were investigated. These films were deposited on glass substrates using either rf or dc magnetron sputter deposition. The deposition time and the target-to-substrate distance were varied to obtain different total film thicknesses and layer thicknesses. Effects of total film and layer thicknesses on the optical properties and the electrical properties were studied. Theoretical calculations were performed to discuss effect of the thickness on the optical transmittance of the GZO film. As-deposited GZO films show high electrical resistivity, which was greatly reduced by 2 to 3 orders of magnitude due to the introduction of a surface layer of Pt film. However, the optical transmittance was also reduced. This was improved by using an addition anti-refractive GZO surface layer on the Pt/GZO. A GZO/Pt/GZO film exhibiting visible light transmittance greater than 75% and electrical resistivity in the order of 10-4 ohm-cm was obtained.

Abstract:

An investigation is reported by coating BaMgAl10O17:Eu2+ phosphor by silicon oxide using catalyzed atomic layer deposition. Nanoscaled SiO2 films were prepared at room temperature using tetraethoxysilane (TEOS), H2O and NH3 as precursors, reactant gas and catalyst, respectively. AES analysis showed the surface composition of coated phosphor was silicon oxide. In TEM and FE-SEM analysis, the growth rate was about 0.7 Å/cycle and the surface morphology became smoother and clearer than that of uncoated phosphor. The photoluminescence intensity (PL) increased up to 11.04% as ALD cycle increased up to 200 ALD cycle. This means that the reactive surface of uncoated phosphors is uniformly grown with stable silicon oxide to reduce the dead surface layer without change of bulk properties. Moreover, it is found that nanoscaled SiO2 films are quite effective for the improvement of the aging characteristics of photoluminescence.

Abstract:

Thin film stress is often seen as an unwanted effect in micro- and nanostructures. Since recent years, we could employ thin film stress as a useful tool to create nanowires. By creating stress at predetermined breaking points, e.g., in microstructured photo resist thin films, cracks occur on the nanoscale in a well defined and reproducible manner [ ]. By using those as a simple mask for thin film deposition, nanowires can be created. More recently this fabrication scheme could be improved by utilizing delamination of the thin film, in order to obtain suitable shadow masks for thin film deposition in vacuum [ ]. Now, these stress based nanowires can be integrated in microelectronic devices and used as field effect transistors or as hydrogen sensors [ ]. For the functional part of the sensor, it was proposed that thin film stress created by hydrogen adsorption in the nanowire is the driving force. In terms of function, thin films can be also applied on free standing nanoscale whiskers or wires to modify their mechanical features or adding additional functionality. As a second example for the utilization of thin film stress, recent experiments on a piezoelectric and magnetostrictive material combination will be presented. These piezoelectric-magnetostrictive nano-composites are potential candidates for novel magnetic field sensors [ ]. In these composites the magnetostriction will be transferred to the piezoelectric component, resulting in a polarization of the piezoelectric material, that can be used as the sensor signal. The results of two different composite layouts will be presented and discussed with a special focus on the comparison between classical macroscopic composites and the novel nanocomposites.

Abstract:

Structural, electrophysical and thermoelectric properties of nanoscaled In2O3films doped by Sn and Zn were studied. Thin films based on In2O3-SnO2and In2O3-SnO2-ZnO systems were prepared by spray pyrolysis method from water solutions of metal chlorides. It was confirmed that In2O3-based films, especially the In2O3:Sn ones, are promising material for applications related to thermoelectricity. The power factor of obtained films was found to be on the level of the best samples prepared on the base of ITO system.

Abstract:

In order to prepare a time decay-resistant electromagnetic shielding (ES) fabric with good handle, moisture permeability and antibacterial properties, Cu, Ag, Ag/Cu and Ag/Cu/Ag films were deposited on PET non-woven by sputtering in screening experiment. Considering the post continues processing, this study focuses on discharge parameters optimum for a limited short time. Relationship was studied between deposited rate and ES effectiveness (ESE) for the four metallic films on various substrates. The metal deposit greatly relays on the chemical nature of the substrate and target metal category. The deposited metal rate on metal is larger than that on PET. In comparison with single metallic film, the dB value of multi-metallic film obtained for same time even for more time remarkably dropped. Therefore, an Ag-coated PET no-woven was finally fabricated as the multi-functional fabric with anti-decay ESE. The multi-functional PET no-woven with good handle obtained for 3min. by optimizing other parameters exhibits higher ESE, good anti-bacterial and moisture permeability.

Abstract:

The thermally activated formation of nanoscale CoPt alloys was investigated, after deposition of self-assembled Co nanoparticles on textured Pt(111) and epitaxial Pt(100) films on MgO(100) and SrTiO3(100) substrates, respectively. For this purpose, metallic Co nanoparticles (diameter 7 nm) were prepared with a spacing of 100 nm by deposition of precursor-loaded reverse micelles, subsequent plasma etching and reduction on flat Pt surfaces. The samples were then annealed at successively higher temperatures under a H2 atmosphere, and the resulting variations of their structure, morphology and magnetic properties were characterized. We observed pronounced differences in the diffusion and alloying of Co nanoparticles on Pt films with different orientations and microstructures. On textured Pt(111) films exhibiting grain sizes (20–30 nm) smaller than the particle spacing (100 nm), the formation of local nanoalloys at the surface is strongly suppressed and Co incorporation into the film via grain boundaries is favoured. In contrast, due to the absence of grain boundaries on high quality epitaxial Pt(100) films with micron-sized grains, local alloying at the film surface was established. Signatures of alloy formation were evident from magnetic investigations. Upon annealing to temperatures up to 380 °C, we found an increase both of the coercive field and of the Co orbital magnetic moment, indicating the formation of a CoPt phase with strongly increased magnetic anisotropy compared to pure Co. At higher temperatures, however, the Co atoms diffuse into a nearby surface region where Pt-rich compounds are formed, as shown by element-specific microscopy.

Abstract:

The formation of nanoscaled one-dimensional structure constituting the thin films of ZnO via a RF magnetron sputtering process is demonstrated. A detailed analysis of these films has been carried out by exploiting the techniques of ellipsometry, scanning and transmission electron microscopy (SEM, TEM), high-resolution TEM, and scanning tunneling microscopy (STM). The importance of substrate materials due to the nanomorphologies as rods and wires on the substrates as amorphous quartz and silicon, respectively, has been elucidated. It has been exhibited that these fascinating nano-objects (rods, wires) are grown directionally alongc-axis of hexagonal lattice of ZnO. The nucleation and growth mechanisms of these nano-objects have been discussed to interpret the present results.

Abstract:

Ba(Ti1−xSnx)O3 (0 ≤ x ≤ 0.3) thin films were deposited on a platinized silicon substrate by a solution deposition process with methoxyethanol, water, and propylene glycol as solvents. Dielectric properties and current–voltage characteristics of the thin films were investigated in conjunction with phase evolution and microstructures by varying heating temperatures and Sn contents (x). Thin films annealed above 700 °C showed a pure perovskite phase with nanoscaled grains (20–30 nm). The dielectric constant of the thin films depended on the Sn content and showed a maximum value of 330 at x = 0.15. The leakage current behavior of an optimum composition corresponding to x = 0.15 was examined by correlating with charge transport mechanisms. Schottky emission was found to be predominant at voltages less than 6.8 V, and Fowler–Nordheim tunneling appeared to be responsible above 6.8 V. The Schottky barrier of the Ba(Ti0.85Sn0.15)O3–Pt interface was determined to be 1.49 eV.

Abstract:

We report the fabrication of nanofeatured polymeric films using nanosphere lithography and ultraviolet (UV) soft-mold roller embossing and show an illuminative example of their application to solar cells. To prepare the nanofeatured template, polystyrene nanocolloids of two distinct sizes (900 and 300 nm) were overlaid on silicon substrates using a spin coater. A lab-made soft-mold roller embossing device equipped with a UV light source was adopted. A casting method was employed to replicate the nanofeatured template onto polydimethylsiloxane, which was used as the soft mold. During the embossing procedure, the roller was driven by a step motor and compressed the UV-curable resin against the glass substrate to form the nanofeatured layer, which was subsequently cured by UV radiation. Polymer films with nanoscaled features were thus obtained. The influence of distinct processing variables on the reproducibility of the nanofeatured films was explored. The empirical outcomes demonstrate that UV soft-mold roller embossing offers a simple yet potent way of producing nanofeatured films.

Abstract:

Abstract In this study, a two-layered thin-film structure consisting of a dispersed nanoscaled Ag2O phase and SnO2 layer (SA) and a mono-composite film layer (CSA) consisting of a nanoscale Ag2O phase in the SnO2 matrix are designed and fabricated for NO2 gas sensor applications. Two-layered and mono-layered SnO2–Ag2O composite thin films were synthesized using two-step SnO2 and Ag2O sputtering processes and Ag2O/SnO2 co-sputtering approach, respectively. In NO2 gas-sensing measurement results, both SA and CSA thin films that functionalized with an appropriate Ag2O content exhibit enhanced gas-sensing responses toward low-concentration NO2 gas in comparison with that of pristine SnO2 thin film. In particular, a gas sensor made from the mono-composite SnO2–Ag2O layer demonstrates apparently higher NO2 gas-sensing performance than that of double-layered SnO2–Ag2O thin-film sensor. This is attributed to substantially numerous p–n junctions of Ag2O/SnO2 formed in the top region of the SnO2 matrix. The gas-sensing response of the optimal sample (CSA270) toward 10 ppm NO2 gas is 5.91, and the response/recovery speeds in a single cycle dynamic response plot are 28 s/168 s toward 10 ppm NO2, respectively. Such a p–n thin-film configuration is beneficial to induce large electric resistance variation before and after the introduction of NO2 target gas during gas-sensing tests. The experimental results herein demonstrate that the gas-sensing performance of p–n oxide composite thin films can be tuned via the appropriate design of composite thin-film configuration.

Abstract:

The aim of the present study was to characterize two kinds of TiN/TiO2 coatings in terms of topography, composition, and electrochemical stability after immersion in simulated body fluid (SBF). Micropatterning of the substrate (Ti-5Al-4V alloy) was done by using electron beam modification (EBM) by scanning electron beam while nanostructured TiN/TiO2 films were deposited over EBM Ti5Al4V substrates using two physical vapor deposition techniques: 1) magnetron sputtering, and 2) cathodic arc and glow-discharge methods. When immersed for 7 and 14 days in SBF at static conditions (37±0.05 °C, pH 7.4), Ca/P ratio of the apatite deposits increased from approximately 1.5 up to near stoichiometric (1.67), respectively. After the initial decrease, the pH of the solution during soaking increased gradually reaching values close to 7.7 for both coatings. However, the weight gain of the samples with Arc coatings after the immersion period in SBF was nearly three times more than those with magnetron deposited coating. The electrochemical potentiodynamic tests performed in SBF indicated a shift in the corrosion potentials towards nobler direction after 7 and 14 days of immersion compared to non-immersed samples, whereas the corrosion current density was slightly increased.

Abstract:

This study is focused on the elaboration of 8 mol.% yttria stabilized zirconia (YSZ) thin films onto porous supporting NiOYSZ anode substrates using pulsed laser deposition (PLD),and their microstructural and electrical characterizations. Better crystallinity and grain connectivity is observed increasing the deposition temperature until best values are obtained at 500°C. The greater relative conductivity enhancement is found at 300-500°C. The observed an increased conductivity at lower temperatures may be caused by a combination of nanoscaled effect of the YSZ thin film and interfacial effects between YSZ thin film and substrate.

CdSe capped with Trisodium citrate (TSC), Triethanolamine (TEA) and ethylenediaminetetraacetic acid (EDTA) nanoparticles were organized by chemical process at ambient conditions. Spin casting technique was used to deposit thin films on substrates from glass at room temperature. The properties of thin films like structural, morphological and optical were described by the transmissionelectron-microscopy, atomic-force-microscopy, X-ray diffraction, FTIR and optical measurements like Photoluminescence and absorption spectrum. The XRD analysis demonstrated that CdSe has a (sphalerite) cubic zinc Blended structure for all agents. FTIR spectrum indicated that nanoparticles capped well with complex agents. AFM results indicate that prepared films were very smooth with roughness about 1 nanometer. The optical band gaps (Eg) was found direct band gaps for all samples, where determined from the absorption, which is equivalent to 2.25 e. V, 2 e. V, and 1.9 e. V. The rise in the value of bandgaps of the thin films that deposited in this work as compared to bulk is due to the effect of quantum confinement. These nanoscaled thin films were found to exhibit high photoluminescence, Its intensity increase within increases of excitation wavelength.

Abstract:

Nanoscaled silicon cone arrays were formed on mirror-polished silicon wafers by plasma etching using hot filament chemical vapor deposition (HFCVD) system. A mixture of CH4 and H2 was introduced during silicon cone formation. AlN films were coated on Si cone arrays using radio frequency (RF) magnetron sputtering system. Scanning electrons microscopy (SEM) was employed to characterize the morphology of silicon cone arrays before and after AlN coating. The field emission characteristics of AlN coated silicon cone arrays，uncoated silicon cone arrays and AlN films were studied and compared, and the silicon cone arrays with AlN coating showed the best enhanced electron emission properties due to the negative electron affinity of AlN coating layer and the high aspect ratio of silicon cone. For AlN coated silicon cone arrays, a slight hysteresis between the upward and downward voltage sweeps was also observed and the field emission currents from AlN coated Si nanocone arrays decreased with the increase of the thickness of AlN films, which could be mainly attributed to the space charge buildup in AlN film with wide band gap.

Abstract:

Chemical bath deposition (CBD) is a fairly simple synthetic route to prepare II-VI semicondutive zinc sulfide thin films, which can be prepared on the flat surface of glass or silicon wafer substrates in the solution containing the precursors of zinc and sulfur ions in terms of ambient conditions of varying acidity. This study particularly aims at the growth dependence and optical property of ZnS thin films in the CBD process by different experiment parameters, whereas we intend to choose suitable types of zinc ionic precursors to be coupled with various CBD parameters such as reaction temperature and time, precursor concentration, types and complexing agents as well as post-deposition heat treatment conditions. Addition of different concentration of ethylenediamine, ammonium sulfate, sodium citrate and hydrazine in the CBD reaction process was used to control the adequate growth rate of ZnS thin films. As a consequence, the rapid thermal annealing was employed to enhance the film uniformity and thickness evenness, transmittance and the energy gap of ZnS samples. The results would lead to a potential application of buffer layer for the Cu (In,Ga)Se2 based thin film solar cells. The analytic instrument including SEM, AFM, UV-VIS were used to examine the CBD-derived nanosized ZnS buffer layers for the thin film solar cells. The ZnS thin films prepared by the chemical bath deposition in this study results in film thickness of 80 ~ 100 nm, high transmittance of 80~85% and the energy gap of 3.89 ~ 3.98 eV.

Abstract:

Using molecular dynamics (MD) simulation, the austenitic and martensitic phase transitions in pure iron (Fe) thin films containing coherent twin boundaries (TBs) have been studied. Twelve thin films with various crystalline structures, thicknesses and TB fractions were investigated to study the roles of the free surface and TB in the phase transition. In the austenitic phase transition, the new phase nucleates mainly at the (112)bcc TB in the thicker films. The (111¯)bcc free surface only attends to the nucleation, when the film is extremely thin. The austenitic transition temperature shows weak dependence on the film thickness in thicker films, while an obvious transition temperature decrease is found in a thinner film. TB fraction has only slight influence on the austenitic temperature. In the martensitic phase transition, both the (1¯10)fcc free surface and (111)fcc TB attribute to the new body-center-cubic (bcc) phase nucleation. The martensitic transition temperature increases with decreased film thickness and TB fraction does not influent the transition temperature. In addition, the transition pathways were analyzed. The austenitic transition obeys the Burgers pathway while both the Kurdjumov–Sachs (K–S) and Nishiyama–Wassermann (N–W) relationship are observed in the martensitic phase transition. This work may help to understand the mechanism of phase transition in the Fe nanoscaled system containing a pre-existing defect.
