Abstract

Time resolved infrared spectra of $S1H_{3}$ were observed in pulsed discharge silane plasmas using diode laser kinetic spectroscopy. The rate of recombination plus disproportionation reactions was determined for the first time, together with the diffusion constants of $SiH_{3}$ in hydrogen and argon. These fundamental quantities will be useful in discussing CVD mechanisms leading to amorphous silicon.
