摘要
Hydrogenated amorphous silicon carbide (a-Si1-xCx:H) films were prepared by hot-wire chemical vapor deposition (CVD) using methane as a carbon source at a low tungsten temperature of 1400 degreesC, and the effect of gas pressure on the film properties and structure was investigated. The infrared absorption spectra revealed that Si-C bonds increased with increasing gas pressure from I to 4 Torr. Consequently, the optical band gap increased from 1.8 to 2.2 eV. The deposition rate was 1.2 nms(-1) at 4 Torr and higher than that in plasma-enhanced CVD deposition by about one order of magnitude. It was found that a-Si1-xCx:H films with an optical band gap over 2.0 eV could be easily prepared by control of gas pressure even at a low tungsten temperature of 1400 degreesC and at a higher deposition rate.
