The results of steady state and transient photoconductivity characteristics of As-S-Sb thermally deposited amorphous thin films are presented. The lux-ampere characteristics of the steady-state photoconductivity are described by the power low dependence σ = B • Fγ with the power index [equation] where T* is the parameter of localized states distribution. The spectral characteristics of the photoconductivity for As-S-Sb thin films represents a curve with a broad peak centered at 2.50-1.93 eV, and is shifted in the low energy region of the spectrum when the Sb content is increasing in the glass alloy. The transient characteristics of As-S-Sb amorphous films are discussed in frame of trap-controlled model for an exponential distribution of localized states in the band gap of amorphous semiconductor.
