Abstract :
Under non-illumination conditions, dying oscillations of electric current in PbSnTe:In film structures were observed upon applying a constant voltage to the samples. A model for the transition of the structures to a stationary state is discussed, in which capture of electrons injected out of contacts at energy-distributed traps is assumed; this capture leads to non-monotonic variation of polarizability and injection current in PbSnTe:In.
