摘要：
Films of a-SixC1-x:H with different carbon contents were deposited by an ultrahigh vacuum plasma enhanced chemical vapour desposition system and characterized by means of the following experimental techniques: photothermal deflection spectroscopy, constant photocurrent method, optical modulation spectroscopy and electron spin resonance. The results include data on optical gap, Urbach tail energy, thermal activation energy of dark conductivity, density and distribution of defects and quantum efficiency-mobility-lifetime product. Comparison of the data obtained with the different techniques is presented and discussed.
