2014 Novel methods for the material synthesis, crystal growth and film preparation of CuInS2 were developed, some of their properties were characterized. CuInS2 single crystals were grown by iodine vapour transport. The habit-planes were determined to be (112) and (110). The lattice parameters were determined to be a = 5.517 Å, c = 11.122 Å (tetragonal). The as-grown crystals were n-type with r...

A tabletop high-brightness line-emitting laser-plasma soft x-ray source utilizing single microscopic droplets as target is shown to produce several orders of magnitude less debris than conventional-target sources. Quantitative measurements of debris deposition rates and x-ray flux at different directions around the droplet plasma are presented. With ethanol droplets and a 10 HZ, 70 m.l/pulse la...

AlNxOy thin films were produced by DC reactive magnetron sputtering, using an atmosphere of argon and a reactive gas mixture of nitrogen and oxygen, for a wide range of partial pressures of reactive gas. During the deposition, the discharge current was kept constant and the discharge parameters were monitored. The deposition rate, chemical composition, morphology, structure and electrical resis...

This paper describes the results of room temperature joining of TiO2 / SiO2 IRF by sputter deposition with a special emphasis of improvement of adherence at the interface. This multilayer system is designed to shield the infrared energy of solar spectrum by interference reflection. The abrasion resistance of the multilayer stacks was also estimated by the Haze value after the Taber abrasion tes...

We report on the optical constants and their dispersion profiles determined from spectroscopic ellipsometry (SE) analysis of the 20%-titanium (Ti) doped of tungsten oxide (WO3) thin films grown by sputter-deposition. The Ti-doped WO3 films grown in a wide range of temperatures (25-500 °C) are amorphous and optically transparent. SE data indicates that there is no significant interdiffusion at t...

The hydrophilicity of vertically aligned metal nanorods with sharp nanotips were investigated experimentally. Ruthenium and platinum nanorod arrays were deposited on flat silicon substrates using oblique angle sputter deposition. We show that the effects of nanotips on nanorods should be considered in the "hemiwicking" model for hydrophilic metallic samples. With the influence of nanotips, we s...

Ga:La:S:Cu films have been prepared by sputter deposition. Amorphous thin films were fabricated with Cu concentrations as high as 66 at.%. The electrical phase change properties of these films have been investigated. The electrical resistivity of these materials is 200 Om in the amorphous state and 40 Om in the crystalline state. The crystallisation time was measured using an optical pump probe...
