摘要
Abstract
A series of hydrogenated amorphous silicon carbide thin films with different C/Si ratio were fabricated using plasma-enhanced chemical vapor deposition system by changing the ratio of methane and silane. The changes of microstructures were characterized by the Raman, X-ray photoeleetron spectroscopy (XPS) and Fourier-transform infrared (FT-IR) spectra. It was found that the optical band gap of the film becomes wider as the C-H bond and Si-C bond content increase, and it reaches as high as.2.4 eV when the ratio of methane and silane is 10.关键词
