It is known that the increase in electrical conductivity in semiconductor materials occurs in two ways: by increasing their temperature, as well as by increasing the number of impurities and defects in the crystals of these materials. From this point of view, the crystals of zinc diphosphide and cadmium can be attributed to promising semiconductor materials. In our case, crystals of α - ZnP2, which were grown by sublimation in two temperature furnaces, were selected as the object of the study, electrically active defects were identified, causing the appearance of short-circuit relaxation currents during the heating process. Spontaneous polarization, which generates short-circuit thermostimulated currents, is caused by disturbances of dynamic equilibrium in the electronic and lattice subsystems of the crystal of zinc diphosphide.
