Over the past decade, many applications were intended for filtration by membrane technology especially the thin film composite (TFC) membranes. In advanced developments of thin film membranes, an attempt was made to spread a new generation of membranes called thin film nano composite (TFN) membranes. However, in the last generation of TFNs, an ultrathin selective film of nanoparticles is coated...

The capability to fabricate photovoltaic (PV) solar cells on a large scale and at a competitive price is a milestone waiting to be achieved. Currently, such a fabrication method is lacking because the effective methods are either difficult to scale up or expensive due to the necessity for fabrication in a vacuum environment. Nevertheless, for a class of thin film solar cells, in which the solar...

The processes of silver diffusion into thin-film structures (As2S3)0,995Sn0,005 under the X-ray radiation were studied. Thin-film layers silver, about 12 nm thick, deposited by vacuum thermal evaporation on surface. thin layer irradiated with in range absorbed doses 0,3-0,6 Gy using tube a copper anode (voltage 45 kV, current 40 mA) as an source without any filters (the continuous spectrum X-ra...

Fabrication of a monocrystalline silicon based heterojunction film at room-temperature in a time-efficient manner is desirable for energy and environmental considerations. In this report, a gas-solid phase direct elemental reaction (DER) route to realize this aim by firstly depositing an elemental copper layer on a monocrystalline silicon surface followed by a reaction with iodine vapor is desc...

Abstract: Different thickness of Cu2S thin films were prepared by vacuum evaporation under a pressure of 10-6 torr at an evaporation rate of 3Å /sec. Cu2S has direct band gap energy and indirect band gap energy at 1.2eV and 1.8 eV respectively. This paper presents the analysis of structural and optical properties of the Cu2S thin film by X-ray diffractometer (XRD) and UV-Vis-NIR Spectrophotomet...

titanium nitride-copper (tin-cu) nanocomposite films were deposited onto stainless steel substrate using hollow cathode discharge ion plating technique. the influence of cu content in the range of 2-7 at.% on the microstructure, morphology and mechanical properties of deposited films were investigated. structural properties of the films were studied by x-ray diffraction pattern. topography of t...

we report the growth and characterization of cu nanoparticles thin film of on glass substrate by pulse laser deposition method. the cu thin film prepared with different energy 50, 60, 70, and 80 mj. the energy effect on the morphological, structural and optical properties were studied by afm, xrd and uv-visible spectrophotometer. surface topography studied by atomic force microscopy revealed na...
