Two types of samples were studied. In the material with higher donor concentration four electron traps labelled by us as E1 to E4 were found. For the traps E2 and E3 energies obtained from Arrhenius plots are equal to 0.24 eV and 0.36 eV, respectively. Electric field enhanced electron emission from the levels E1 and E4 was observed and described in terms of Frenkel-Poole mechanism. Capture process from the traps E2 was found to be thermally activated with energetic barriers equal to 0.20 eV for E2.
