Laser-induced chemical vapour deposition of Si/C/H materials from monoorganylsilanes
Abstract
Laser-induced photolysis of monoorganylsilanes RSiH3(R = H2C
CH, HC
C, ClHC
CH and H2C
CHCH2) produces thin Si/C/H films, thought to be saturated polycarbosilanes of low hydrogen content, and formed from unsaturated transients generated upon elimination of hydrogen and ethyne from the RSiH3 molecules. The films incorporate oxygen upon exposure to the atmosphere.
