Abstract
The results of investigation of isothermal currents and charge accumulation in In-MnGa2Se4-In sandwich structures are presented. The obtained data are analyzed on the basis of the theory of isothermal currents and the relay-race mechanism of charge transport. It is shown that the dark-current relaxation in MnGa2Se4 single crystals is associated with charge accumulation at deep levels due to injection from the cathode. The following parameters are determined: the contact capacitance C k = 2 × 10−13 F, the charge-accumulation-layer thickness d k = 4 × 10−6 cm, and the drift charge-carrier mobility μch = 3 × 10−8 cm2 V−1 s−1 in MnGa2Se4 single crystals.
