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:
Dünne Filme aus konjugierten Molekülen werden vermehrt in der organischen Optoelektronik, Bio-Sensorik und Oberflächenmodifikationen eingesetzt. Jedoch steckt das nanoskopische Verständnis von elementaren Prozessen bzgl. des molekularen Wachstums, der Film-Stabilität und thermisch-mechanischer Eigenschaften noch in den Kinderschuhen. Im ersten Teil dieser Arbeit nutzen wir Echtzeit in situ spekulare und diffuse Röntgenstreuung in Kombination mit Kinetik-Monte-Carlo Simulationen, um die Nukleation und das Multilagen-Wachstum von C60 zu studieren. Wir quantifizieren einen konsistenten Satz von Energieparametern, die die Oberflächenprozesse während des Wachstums beschreiben: eine effektive Ehrlich-Schwoebel Barriere von EES = 110 meV, eine Oberflächendiffusions-Barriere von ED = 540 meV und die Bindungsenergie von EB = 130 meV. Durch die Analyse der Teilchendynamiken finden wir, dass die laterale Diffusion ähnlich derer von Kolloiden ist, jedoch weist die Stufenkanten-Diffusion eine atom-ähnlichen Schwoebel-Barriere auf. Außerdem haben wir für die erste Monolage ein thermisch-aktiviertes Dewetting nach dem Wachstum von C60 auf Mica mit einer effektiven Aktivierungsbarriere von (0.33 ± 0.14) eV für die Aufwärts-Diffusion beobachtet. Im zweiten Teil der Arbeit untersuchen wir die thermomechanischen Eigenschaften der supra-molekularen Anordnung von dem organischen Halbleiter PTCDI-C8. Temperaturabhängige GIXD-Experimente decken einen außergewöhnlich großen positiven und negativen thermischen Expansionskoeffizienten der Kristallstruktur auf. Die Moleküle vollführen kooperative rotierende Bewegungen als Reaktion auf die Temperaturänderung, die zu dieser anomalen thermischen Expansion führen. Unsere Beschreibung der Bewegungen einzelner adsorbierter Moleküle während des Wachstums und der kooperativen Bewegungen einzelner Moleküle in supra-molekularen Ensembles auf der molekularen Skala wird die weitere Arbeit auf dem Weg zu funktionalen molekularen dünnen Filmen beleben.
Thin films of conjugated molecules are increasingly used in organic optoelectronics, biosensing and surface modification. However, nanoscopic understanding of elementary processes regarding the molecular film growth, the stability of these films and regarding the thermal and mechanical properties of supra-molecular assemblies are in its infancy. In the first part of this thesis we use real-time in situ specular and diffuse X-ray scattering in combination with kinetic Monte Carlo simulations to study C60 nucleation and multilayer growth. We quantify a consistent set of energy parameters, which describe the surface processes during growth, yielding an effective Ehrlich-Schwoebel barrier of EES = 110 meV, a surface diffusion barrier of ED = 540 meV and a binding energy of EB = 130 meV. Analysing the particle-resolved dynamics, we find that the lateral diffusion is similar to colloids, but step-edge crossing is characterized by an atom-like Schwoebel barrier. Furthermore, a thermally-activated post-growth dewetting for C60 on mica has been observed for the first monolayer with an effective activation barrier for upward interlayer transport of (0.33 ± 0.14) eV. In the second part we investigate the thermomechanical properties of the supra-molecular assembly of the organic semiconductor PTCDI-C8. Temperature-dependent Grazing Incidence X-ray Diffraction (GIXD) experiments reveal extraordinary large positive and, surprisingly, negative thermal expansion coefficients of the thin film crystal structure. The molecules perform temperature-controlled cooperative rotational motions leading to the change of the molecular crystal structure at different temperatures. We hope that our molecular scale picture of the movement of single ad-molecules during growth and the cooperative motions of single molecules in supra-molecular ensembles will stimulate further work towards the optimized, rational design of functional molecular thin films and nanomaterials.

Abstract:
As optoelectronic components become nano-dimensional, controlling the coupling between light and matter at the nanoscale has become a major technological challenge, as well as the subject of theoretical studies. The aim of this work is threefold. First, to assess the suitability of ferroelectric thin films - Barium Strontium Titanate (BST), and Strontium Barium Niobate (SBN), as active media for plasmonic devices. Second, to find suitable thin film electrodes for such devices, by exploring and optimizing the plasmonic behaviour of already known conductive materials, conductive oxides (Strontium Ruthenate - SRO), and transitional metal nitrides (Titanium nitride - TiN). Third, to optimize the deposition process of metallic (Silver – Ag) films, so as to improve their smoothness, and thus their suitability for plasmonic applications and lithography in general. SBN ceramic targets were sintered. SBN and BST films were deposited by PLD and ellipsometry and normal incidence reflectometry were used to examine their optical tunability. Ellipsometry was further used to measure the effects of the residual strain of the BST thin films on their optical properties. BST and SBN films were found to exhibit a birefringence under bias along the direction of growth. A residual strain variation along the films’ direction of growth was inferred from an observed non-linear change in the refractive index of BST films along that same direction. SRO and TiN films were fabricated using PLD and reactive magnetron sputtering, respectively. The effects of the deposition pressure upon structure, charge carrier concentration and mobility, and optical properties were studied using X-ray diffraction (XRD), Hall-effect measurements, and ellipsometry. The optical properties of SRO were explained based on electron concentration and structure. SRO was confirmed as a promising plasmonic material, for applications in the near infrared range and at elevated temperatures. The influence of the deposition temperature upon the optical properties of TiN films was shown. Films grown at high temperature (800oC) had quasi-metallic optical properties, while films grown at room temperature exhibited well defined plasmon bandwidth, between two distinct Epsilon-near-zero (ENZ) frequencies, which has been linked to the uniform oxidation of the samples). Finally, Ag thin films were deposited using magnetron sputtering, in an Ar/He atmosphere. The effect of the sputtering gas ratio on the films structure, morphology and reflectivity was studied using XRD, Atomic force microscopy (AFM) and visual-range normal incidence reflectometry. The addition of Helium to the sputtering atmosphere was found to reduce the roughness of Ag films and improve their reflectivity, due to the Penning effect present in the Ar-He plasma. The work undertaken has, by developing new plasmonic materials (SRO, oxidized TiN), and expanding the knowledge of the behaviour (BST) and fabrication (Ag) here has paved the way for the development of active plasmonic devices.

Abstract:
Modification of planar graphitic carbon surfaces by the attachment of molecular films has been investigated in this work. Molecular layers have been grafted to glassy carbon (GC) and pyrolyzed photoresist film (PPF) by employing a range of techniques, which involved electrochemically and photochemically assisted procedures. Modification methods involve the electrochemical reduction of aryldiazonium salt, electrochemical oxidation of arylcarboxylate and photolysis of alkene, alkyne and azide on carbon surfaces. For these methods, it is proposed that reactive species are generated by the procedures, which leads to the grafting of modifiers to the carbon surfaces. A selection of molecular species was grafted to GC and PPF by these method containing different terminal R-functional groups that include —COOH, -NO₂, -NH₂, and —NCS. The grafted R-functional groups permit for further chemical reactions on the surface. Electrochemically and photochemically grafted films were examined with a combination of water contact angle measurements, cyclic voltammetry, X-ray electron spectroscopy XPS, optical microscopy, scanning electron microscopy SEM and atomic force microscopy AFM. Film properties such as surface concentration, film thickness, wettability, chemical composition and reactivity were characterized by the above mentioned techniques. Films electrochemically prepared from aryldiazonium salts and arylcarboxylates, under the conditions applied in this work, formed loosely packed multilayers with typical film thicknesses of les than 5 nm. Photochemically grafted films prepared from alkenes and azides, in general, formed loosely packed monolayers with film thicknesses of less than 2 nm. Loosely packed multilayers were also prepared from alkene and alkyne by photochemical procedures. ii Chemical reactions on grafted films were demonstrated and analyzed by a combination of the above mentioned characterization techniques. In particular, the reduction of nitrophenyl (NP)films, amine-coupling reactions, photoactivation of grafted films with oxalyl chloride and electrostatic assembly of anionic gold nanoparticles were investigated. Selected chemical reactions permitted identification and evaluation of the grafted layers, and demonstrated the ability to control the immobilization of chemical species. Microscale chemical patterning of two different types of modifiers on carbon surfaces was demonstrated using photolithographical techniques that utilized photochemical reactions with azides. Patterns of line-arrays with line widths of hundreds of micrometers to 10 µm were formed.

Abstract:
Ultrashort-pulsed laser irradiation on metals creates a thermal non-equilibrium between electrons and the phonons. Previous computational studies used the two-temperature model and its variants to model this non-equilibrium. However, when the laser pulse duration is smaller than the relaxation time of the energy carriers or when the carriers mean free path is larger than the material dimension, these macroscopic models fail to capture the physics accurately. In this paper, the non-equilibrium between energy carriers is modeled via numerical solution of the Boltzmann Transport Model (BTM) for electrons and phonons which is applicable over a wide range of length and time scales. The BTM is solved using the Discontinuous Galerkin Finite Element Method for spatial discretization and the three-step Runge Kutta temporal discretization. Temperature dependant electron-phonon coupling factor and electron heat capacity are used due to the strong electron-phonon non-equilibrium considered in this study. The results from the proposed model is compared with existing experimental studies on laser heating of macroscale materials. The model is then used to study laser heating of gold films, by varying parameters such as the film thickness, laser fluence and pulse duration. It is found that the temporal evolution of electron and phonon temperatures in nanometer size gold films are very different from the macroscale films. For a given laser fluence and pulse duration, the peak electron temperature increases with a decrease in the thickness of the gold film. Both film size as well as laser fluence significantly affect the melting time. For a fluence of 5000 J/m2, and a pulse duration of 75 fs, gold films of thickness smaller than 200 nm melt before reaching electron-phonon equilibrium. However, for the film thickness of 2000 nm, even with the highest laser fluence examined, the electrons and phonons reach equilibrium and the gold film does not melt.

Abstract:
We present experimental results to describe the stress relaxation behavior of thin (125 nm) freestanding gold films at room temperature. The experiments were performed inside a field emission scanning microscope using a MEMS-based test bed which is only 3mm × 10mm in size. The effect of stress relaxation on the young’s modulus of gold thin films is observed. The thin film specimen used in the experiment is co-fabricated with the micromechanical loading device and hence eliminates problems of alignment and gripping. Freestanding thin films provide us with information about the mechanical behavior of thin films in the absence of substrate effects.

Abstract:
Thin films of nanoscale thickness are common in integrated systems and devices. Subjected to interactions of diverse physical origins, the nanoscale thin films often undergo structural and/or morphological instability and develop a variety of surface patterns. Two examples are discussed in this paper. An epitaxial thin film undergoes surface roughening and form self-assembled quantum dots [1]. A thin metal film bonded to a polymer substrate develops various wrinkle patterns [2]. We develop nonlinear models and numerical methods to simulate the evolution processes. The results reveal very rich dynamics of surface pattern formation and suggest potential means for the control and making of ordered patterns.

Abstract:
Thin films in general exhibit different thermal properties compared to bulk due to size effect [1–3]. In this study, the thermal conductivity of sputtered Sn films of thickness 500 nm ± 50 nm and 100 nm ± 20 nm are obtained from 55K to 300K and from 40K to 310K, respectively, using the three omega method. The thermal conductivity of 500 nm thin film at room temperature is 46.2 ±4.2 W/m-K, which is lower when compared to its bulk value of 63 W/m-K, and increases gradually as the temperature is lowered to 55K. In contrast, the thermal conductivity of the 100 nm thin film exhibits even reduced thermal conductivity, 36 ± 2.88 W/m-K at 300K, when compared to the 500 nm film, and decreases as the temperature is lowered. The reduction in thermal conductivity of Sn thin film may be due to the pronounced effects of electron scattering at the grain boundaries as well as the twin boundaries in addition to the scattering from the boundary surface at lower temperatures. These experimentally determined thermal conductivities are compared to models that take into account size effects on thermal conductivity of metallic films based on electronic scattering as proposed by Fuchs-Sondheimer (FS), Mayadas-Shatzkes (MS) and Qiu and Tien (QT). The experimentally measured thermal conductivity of Sn films is in good agreement with the MS model indicating the importance of the grain boundary scattering. Thickness measurements are obtained by ellipsometry and profilometer. The estimation of the mean grain size in both films and the evidence of twin boundaries are obtained by Atomic Force Microscopy.

Abstract:
Heat transport of dielectric thin films in 30–300 nm thick is characterized in the temperature range of 74–300 K using the 3ω method, which is a simple method to measure the cross-plane thermal conductivity of dielectric thin films. Dielectric film samples of two kinds, deposited on Si substrates using plasma enhanced chemical vapor deposition (PECVD) and grown by thermal oxidation, were measured. In order to broaden the application of 3ω method, 3ω method system was combined with cryogenics system to measure temperature dependent material property. SiO2 films, prepared by thermal oxidation and PECVD, have been put and measured in the cryogenics system. The apparent thermal conductivity, intrinsic thermal conductivity, and interface resistance have been analyzed in different temperature. For this experiment, we discovered the thermal conductivity of PECVD SiO2 films is smaller than the thermal conductivity of SiO2 grown by thermal oxidation, because the porosity of thermal SiO2 is smaller than PECVD SiO2. The apparent thermal conductivity of SiO2 film decreases with film thickness. The thickness dependent thermal conductivity is interpreted in terms of a small interface thermal resistance RI. For SiO2 films, the thermal conductivity decreases if the temperature decreases, because the mean free path of heater carriers increases.
