Résumé :
In this paper, we present a detailed study of high quality (110) ZnO films, epitaxially grown on R-plane sapphire substrates by metal-organic chemical vapor deposition (MOCVD). The epitaxial relationships are (11 0 ) ZnO//( 01 2 ) Al2O3 and [0001] ZnO//[011] Al2O3 as confirmed by X-ray diffraction (θ-2θ, and ϕ-scan) and high-resolution cross-sectional transmission electron microscopy (HR-TEM). Low temperature photoluminescence (PL) indicates the ZnO thin films are almost strain free. Optical absorption and reflection measurements with linearly polarized light indicate a strong optical anisotropy. The polarization rotation towards the C-axis associated with the optical anisotropy is utilized to demonstrate an optically addressed ultra-fast, ultraviolet light modulator.

Résumé :
AbstractIn this paper, the application of recently developed x-ray diffraction techniques to the characterization of thin epitaxial films will be discussed. The double-crystal diffractometer, with high resolution in the non-dispersive arrangement, enables the materials scientist to study epitaxial systems having a very small mismatch with high precision. A key part of the characterization of an epitaxial film is the determination of the strain tensor by measuring lattice spacing! in various directions The determination of strain and composition profiles in ion-implanted films, epitaxial layers and superlattices by rocking-curve analysis will also be reviewed. Grazingincidence diffraction, an emerging new technique, can be used to obtain structural details parallel to the interface on films with thicknesses ranging down to a few atomic layers. The synchroton has now become increasingly available as a powerful source of x radiation which will facilitate the application of conventional and grazing-incidence diffraction to ultra-thin films.

Résumé :
Materials’ properties may differ in the thin-film form, especially for epitaxial ultra-thin films, where the substrates play an important role in their deviation from the bulk quality. Here by molecular beam epitaxy (MBE) and scanning tunneling microscopy/spectroscopy, we investigate the growth kinetics of ultra-thin tellurium (Te) films on SrTiO3 (STO) (001). The MBE growth of Te films usually exhibits Volmer–Weber (VW) island growth mode and no a-few-monolayer film with full coverage has been reported. The absence of wetting-layer formation in the VW growth mode of Te on STO (001) is resulted from its low diffusion barriers as well as its relatively higher surface energy compared with those of the substrate and the interface. Here we circumvent these limiting factors and achieve the growth of ultra-thin β-Te films with near-complete coverages by driving the growth kinetics to the extreme condition. There is a critical thickness (3 monolayer) above which the two-dimensional Te films can form on the STO (001) substrate. In addition, the scanning tunneling spectra on the ultra-thin Te film grown on STO exhibits an enormously large forbidden gap compared with that grown on the graphene substrate. Our work establishes the necessary conditions for the growth of ultra-thin materials with similar kinetics and thermodynamics.

Résumé :
In our study, for the first time we demonstrate the advantages of using a compliant hybrid substrate of porSi/SiC to grow high-quality ultra-thin nanostructured AlxGa1−xN/GaN heterostructures using molecular beam epitaxy with plasma-activated nitrogen. Comparison of our experimental results obtained by micro-Raman spectroscopy, deconvolution, and the fitting of the experimental Raman spectra and subsequent calculations with information from already established literature sources show that the use of such a hybrid SiC/porSi substrate has a number of undeniable advantages for the growth of ultra-thin AlxGa1−xN/GaN nanoheterostructures without requiring the use of thick AIIIN buffer layers. Direct growth on a hybrid compliant substrate of SiC/porSi leads to a substantial relaxation in the elastic stresses between the epitaxial film, porous silicon, and silicon carbide, which consequently affects the structural quality of the ultra-thin AlxGa1−xN/GaN epitaxial layers. The experimental and computational data obtained in our work are important for understanding the physics and technology of AlxGa1−xN/GaN nanoheterostructures and will contribute to their potential applications in optoelectronics.

Résumé :
Oxide ultra-thin film surfaces have properties and structures that are significantly different from the terminations of the corresponding bulk crystals. For example, surface structures of epitaxial ultra-thin oxide films are highly influenced by the crystallinity and electronegativity of the metal substrates they grown on. Some enhanced properties of the novel reconstructions are related to catalysis, sensing and microelectronics, which has resulted in an increasing interest in this field. Ultra-thin TiOx films were grown on Au(111) substrates in this work. Two well-ordered structures within monolayer coverage - honeycomb (HC) and pinwheel - were generated and investigated. Special attention has been paid to the uniform (2 x 2) Ti2O3 HC phase including its regular structure and imperfections such as domain boundaries (DBs) and point defects. Linear DBs with long-range repeating units have been observed; density functional theory (DFT) modelling has been used to simulate their atomic structures and calculate their formation energies. Rotational DBs/defects show up less frequently, however a six-fold symmetrical 'snowflake' DB loop stands out. Two types of point defects have been discovered and assigned to Ti vacancies and oxygen vacancies/hydroxyl groups. Their diffusion manners and pairing habits have been discussed within an experimental context. The results of growing NbOx ultra-thin films on Au(111) are also presented in this thesis. An identical looking (2 x 2) HC structure to the Ti2O3 ultra-thin film has been formed; a stoichiometry of Nb2O3 is suggested. Another interesting reconstruction is a hollow triangle structure. Various sizes have been found, and sides of these equilateral triangles all show a double-line feature aligned along the { 1 ₁⁻ } directions of the Au(111) lattice. Chemical composition characterisations of NbOx thin films are still required as is DFT modelling. Experimental techniques used in this thesis include scanning tunnelling microscopy (STM), low energy electron diffraction (LEED), and X-ray photoelectron spectroscopy (XPS). Ultra-thin oxide films were created by physical vapour deposition (PVD) in ultra-high vacuum (UHV) systems.

Résumé :
The growth of Co (0001) films and Cr2O3 (0001)/Co (0001) has been investigated using surface analysis methods. Such films are of potential importance for a variety of spintronics applications. Co films were directly deposited on commercial Al2O3 (0001) substrates by magnetron sputter deposition or by molecular beam epitaxy (MBE), with thicknesses of ~1000Å or 30Å, respectively. Low Energy Electron Diffraction (LEED) shows hexagonal (1x1) pattern for expected epitaxial films grown at 800 K to ensure the hexagonally close-packed structure. X-ray photoemission spectroscopy (XPS) indicates the metallic cobalt binding energy for Co (2p3/2) peak, which is at 778.1eV. Atomic force microscopy (AFM) indicates the root mean square (rms) roughness of Co films has been dramatically reduced from 10 nm to 0.6 nm by optimization of experiment parameters, especially Ar pressure during plasma deposition. Ultrathin Cr2O3 films (10 to 25 Å) have been successfully fabricated on 1000Å Co (0001) films by MBE. LEED data indicate Cr2O3 has C6v symmetry and bifurcated spots from Co to Cr2O3 with Cr2O3 thickness less than 6 Å. XPS indicates the binding energy of Cr 2p(3/2) is at 576.6eV which is metallic oxide peak. XPS also shows the growth of Cr2O3 on Co (0001) form a thin Cobalt oxide interface, which is stable after exposure to ambient and 1000K UHV anneal.

Résumé :
Vanadium ultra-thin (1-7 monolayers) films are deposited epitaxially on well-defined single crystalline Ag(100) substrate. The topmost layers of the films are studied by electron capture spectroscopy(ECS). ECS is a surface-sensitive technique for the investigation of magnetic order existing at surfaces. It is found that the topmost atomic layer of V(100) films are ferromagnetic for all film thicknesses, in contrast to bulk vanadium which is paramagnetic at all temperatures. The films of thickness of 5 monolayers possess a surface Curie temperature T$\sb{\rm cs}$ = 475.1 K, and the critical behavior of the magnetization of the films is identical to that predicted by the well-known two-dimensional Ising Model of ferromagnet.

Niobium nitride compounds have rich physical properties due to their complexities in stoichiometry and structures. Among these NbxNy compounds, some of them show superconductivity. The δ-NbN phase, with a cubic crystalline symmetry, has a high superconducting transition temperature (TC), up to 17 K. Ultra-thin superconducting δ-NbN film has been widely applied on ultrasensitive devices due to its prominent physical properties, such as having a high superconducting transition temperature, a short intrinsic electron-phonon interaction time, and a high superconducting critical current density. Especially, hot-electron-bolometer (HEB) mixers using -NbN ultra-thin film demonstrate excellent performance on terahertz detection and are used on several astronomical telescopes. In my thesis study, I focused on the fabrication of high quality ultra-thin superconducting -NbN films and characterize their physical properties with the help of Dr. Hsiao-Wen Chang and other members in Dr. Ming-Jye Wang’s research group. We have realized the epitaxial growth of ultra-thin δ-NbN films on (100)-oriented 3C-SiC/Si substrates at temperature around 760°C by DC reactive magnetron sputtering. The deposition rate is about 0.05 nm/s. The δ-NbN films show superconductivity even with a thickness of 2.14 ± 0.03 nm (∼ 5 unit cells). The high-resolution transmission electron microscope images of films confirm excellent epitaxy and are used for estimating films’ thickness and lattice constant. We have investigated the magnetotransport properties of ultra-thin NbN films with the thickness ranging from 2.14 ± 0.03 nm to 4.95 ± 0.03 nm under external magnetic field up to 9 Tesla. From the measured Hall resistances, the carrier concentration, n, of film can be calculated, for example n ~ (4.13 ± 0.04) × 1028 m-3 for 3.84 ± 0.02 nm film. Generally, the TC of film decreases as the film thickness is reduced. The degradation of TC can be explained by the scaling law which describes the competition between disorder and superconductivity. Surprisingly, some distinct oscillations of both TC and ρ20K as a function of film thickness are observed with a period near 0.5 nm, where ρ20K is the resistivity of film at 20 K. The transition temperature of NbN film is suppressed under external magnetic field. The upper critical field at zero temperature, μ0HC2(0), was estimated by using the empirical equation of μ0HC2(T) = μ0HC2(0)(1-t2)/(1+t2), where t = T/TC(μ0H = 0). For example, the μ0HC2(0) of 2.14 ± 0.03 nm film is 8.13 ± 0.16 Tesla. Similar to TC and ρ20K, the μ0HC2(0) of film is also oscillating in thickness. The oscillation of TC, ρ20K, and μ0HC2(0) might be explained by the quantum size effect which was used to explain the oscillation of TC in thickness in other superconducting ultra-thin films.

Résumé :
The flexibility of physical vapor deposition allows fabrication of near ideal structures which can be used to investigate fundamental aspects of the mechanics of materials. One important phenomena which can be addressed is the deformation which occurs during relaxation of epitaxial strains. We have developed a unique sputter deposition system capable of performing in-situ structural characterization using grazing incidence x-ray scattering (GIXS). This gives us the ability to accurately measure lattice parameters of films in the monolayer thickness regime. Using this capability, we have investigated epitaxial orientation relations and coherency stress relaxation in several epitaxial film systems, including Cu on Fe (001), and Co on Pt (111).

Résumé :
Studies on molecular beam epitaxial growth for organic molecules (OMBE) have been attracting attentions as a new fabrication method for preparation of ultra-thin films of organic molecules. Molecular beam epitaxy (MBE) has been developed as a deposition technique for the controlled growth of atomically flat multilayer structures. Recently, this method has been applied to organic materials, while the mechanism of the growth has not been thoroughly understood compared to that of semiconductor. In this report, the growth mechanism of Lead Phthalocyanine (PbPc) thin films onto highly oriented pyrolytic graphite (HOPG) substrate by OMBE method was investigated using in situ refraction high energy electron diffraction (RHEED). RHEED has been widely used for in situ monitoring of the thin film MBE growth. The intensity of the RHEED specular beam spot oscillates according to the layer-by-layer growth[1]. In 1981, Joyce et.al. observed an oscillated phenomena of RHEED intensity with growth of semiconductor for the first time[2]. After that, a lot of work in the semiconductor field have been reported and developed. Although application for organic materials is expected, so far RHEED oscillation studies have only been reported for Copper Phthalocyanine (CuPc) on MoS2 substrate[3]. Therefore, we explored the possibilities of using in situ RHEED observations to investigate the OMBE growth mechanism of PbPc on HOPG system.

Résumé :
Future silicon microelectronics technology will require nanoscale components to achieve ultra large scale integration. The reduction to nanometer scale sizes will be dependent on processing that can be controlled at the atomic level and conformally deposit into high aspect ratio structures. The Si/SiO2 interface is central in silicon technology. Controlled and conformal deposition of SiO2 dielectric layers will be crucial for the fabrication of MOS gate oxides as thin as 50 Å and high aspect ratio trench capacitors in DRAM. Both requirements can be inherently achieved by the technique known as atomic layer epitaxy (ALE)1 or atomic layer processing (ALP) if the deposited film is not epitaxial.
