Abstract :
The results of an experimental study of the kinetics of photocurrent rise in PbSnTe:In films exposed at T=4.2 K to free-electron laser radiation of wavelengths 68, 123, and 205 μm are reported. The obtained data are analyzed within the model of space-charge-limited injection currents that flow in a material with electron traps.
