We have studied structural, electrical, photoelectric and optical properties of two series of polymorphous silicon thin films deposited by PECVD with variation of silane and hydrogen gas mixture pressure and substrate temperature. The change of gas pressure did not affect substantially films' Raman spectra, but resulted in changes of photoconductivity values and spectral dependencies of absorption...
We present the systematic study of the growth mechanism of ZnO nanorods grown on Al2O3 substrates with ZnO homo-buffer, n-GaN and p-GaN interlayers. Vertically aligned ZnO nanorods with diameter of 50 nm and lengths of range of 0.1 - 2 mum were synthesized at the substrate temperature of 350 - 500degC by catalyst-free metal-organic chemical vapor deposition. A thin ZnO film was observed underneath...
