The main research area of the department is "Diagnostics and Formation of Physical Properties of Non-Metallic Materials." The most significant research results in recent years include:
1. The scanning photodielectric spectroscopy method has been further developed. It was demonstrated that measuring the increments of effective values of complex permittivity components at several electric field frequencies significantly expands the energy spectrum of localized charge carrier states in Cd1-xZnxTe crystals and provides additional data on the nature of these states.
2. It was established that the effect of weak electromagnetic radiation generated by a spark discharge in air causes reversible changes in the complex permittivity of Cd1-xZnxTe crystals in the low-frequency range. These changes are attributed to the transition of point defect complexes into a different state. The most active researchers of the department are: O.V. Podshyvalova, O.M. Chuhai, and A.O. Taran.
