Abstract
The experimentally obtained I–V dependences of the dark conductivity of zinc-selenide single crystals have a nonlinear character. The contact phenomena, injection currents, and the Poole-Frenkel effect are considered among the possible causes of such behavior of the I–V characteristics. As a result of investigation, the following is established: (i) the contact between the n-ZnSe single crystal and metallic In is ohmic; (ii) in low fields, the I–V characteristic obeys Ohm’s law; (iii) in strong fields, the dark conductivity of the investigated samples is determined by the Poole-Frenkel effect. Also Poole-Frenkel theory is supplemented for different potentials of interaction of the local center with the charge carrier.
