Nanocrystalline TiN has been imbedded in amorphous silicon nitride matrix to form a super hard nanocomposite thin film (ncTiNya-SiN ) via magnetron sputtering. Adjusting Ti and Si N target power ratio altered film composition, size, amount and x 3 4 distribution of the nc-TiN phase. At a Ti target power density of 5.5 W cm , the Ti to Si N target power ratio should be greater y2 3 4 than unity ...

The oxidation kinetics of two metallic glasses have been studied by ellipsometry and Auger Electron spectroscopy. We have found that the presence of chromium in Fe based alloys has a marked influence on the thickness of corrosion film formed and on the kinetics of film formation. INTRODUCTION measured after various exposures to the high Several authors have reported that amorphous iron based al...

Partial shadowing is one of the problems that are always faced in terrestrial applications of solar photovoltaic (PV). The effects of partial shadow on the energy yield of conventional mono-crystalline and multi-crystalline PV modules have been researched for a long time. With deployment of new thin-film solar PV modules in the market, it is important to understand the performance of new PV mod...

Ultrafast pulsed laser irradiation is demonstrated to be able to produce surface nano-structuring and simultaneous crystallization of amorphous silicon thin film in one step laser processing. After fs laser irradiation on 80 nm-thick a-Si deposited on Corning 1737 glass substrate, the color change from light yellow to dark brown was observed on the sample surface. AFM images show that the surfa...

Amorphous and nanocrystalline silicon films obtained by Hot-Wire Chemical Vapor deposition have been incorporated as active layers in n-type coplanar top gate thin film transistors deposited on glass substrates covered with SiO2. Amorphous silicon devices exhibited mobility values of 1.3 cmVs, which are very high taking into account the amorphous nature of the material. Nanocrystalline transist...

This paper reports the correlation between film thickness, nanostructure and DC electrical properties of copper thin films deposited by PVD method on glass substrate. X-ray diffraction (XRD) and atomic force microscopy (AFM) were used for crystallography and morphology investigation, respectively. Resistivity was measured by four point probe instrument, while a Hall effects measurement system w...

A new device called “Solant” (for SOLar cell – ANTenna) is presented in this paper. It is a combination of thin-film amorphous silicon solar cells and flat printed antennas. A proton irradiation campaign has also been carried out on a series of n-i-p amorphous and p-i-n micromorph [microcrystalline (μc-Si:H) and amorphous (a-Si:H)] silicon tandem solar cells. The effect of thermal annealing on ...

Prolonging wear life of amorphous carbon films under vacuum was an enormous challenge. In this work, we firstly reported that amorphous carbon film as a lubricant layer containing hydrogen, oxygen, fluorine and silicon (a-C:H:O:F:Si) exhibited low friction (~0.1), ultra-low wear rate (9.0 × 10(-13) mm(3) N(-1) mm(-1)) and ultra-long wear life (>2 × 10(6) cycles) under high vacuum. We systematic...

Biaxially oriented CaF2 films have been created by first using an oblique incidence vapor flux to deposit CaF2 onto an amorphous surface to form vertically aligned nanorods which served as seeds to grow a more continuous CaF2 capping layer under a subsequent normal incidence flux deposition. The entire film possesses a unique {111}/121S biaxial texture as shown by X-ray pole figure analysis and...
