Abstract

Modulated photocurrent phase shift measurements (MPC) have been used to probe the valence band tail density of states (DOS) in a-As₂ Se₃. In the absence of obvious structure, use of optical bias to define a ‘thermalisation energy limit’ allows MPC to be used to determine the attempt-to-escape frequency. Computer modelling of steady state and transient photoconductivity reveals inconsistencies in a charged defect interpretation.
