Currents of thermally stimulated depolarization in CaIn2S4 single crystals

The results of investigation into currents of thermally stimulated depolarization in CaIn2S4 monocrystals are presented for the first time. Spectra of thermally stimulated depolarization for In-CaInS4-In structures are measured under T=99 K at various rates of heat, times of polarization and times of expectation following switching off of electrical field up to beginning of measurements of shorting. The main parameters of capture cross section, partial factor, concentration of traps, are determined. It is determined that one may observed a biomolecular mechanism with a strong secondary capture in CaIn2S4 monocrystals. 9 refs.; 4 figs
