Аннотация:MnIn2S4 single crystals have been obtained by chemical transport reaction. Their dark static current-voltage characteristics, temperature dependences of the electroconductivity (sigma(T)), thermostimulated conductivity (TSC) and thermostimulated depolarization (TSD) currents have been investigated in the temperature region from 77 to 310 K. The energy depth of the trapping level E(t), the trap concentration N(t) and the cross-section of the traps S(t) have been determined. The mechanism of the transport of the current in the nonlinear region of the current-voltage characteristic has been found to be attributed to a monopolar and a binary injection.
