Abstract
The single crystals of TlGaTe 2 were grown by the Bridgman method. The current–voltage characteristics were performed for obtained crystals and it was determined that the Poole–Frenkel effect occurs in the nonlinear region of the current in the directions parallel and perpendicular to the crystallographic axis. The calculated values of the concentration of ionized centers [Formula: see text], the mean free path [Formula: see text], the values of the Frenkel coefficient [Formula: see text] and the shape of the potential well in TlGaTe 2 crystals are determined.
