Main area of activity of the structural unit: Production of lamellar and chain AIIIBVI and AIIIBIIICVI2 semiconductor compounds with a mesocopic structure and study their dielectric, relaxor, polarization, piroelectric and electric properties under the effect of external factors (γ-rays, electric field, temperature and etc.); Make devices sensitive to radioactive radiation on the base of the obtained results.

Main scientific achievements of the structural unit: Complex investigation of the dielectric and electric properties of γ-irradiated TllnS2 crystal, study the dynamics of the compounds with relaxor properties. Relaxor state forms at the result of heterogeneous charge distribution in nano-regions at the expense of electric charge localization at defects. Due to the conducted studies a mesocopic structrure of TllnS2 crystal have been obtained and its physical parameters have been investigated. It has been established that by influencing the electronic subsystems the dielectric properties of relaxors can be changed. It is supposed that charge transport in the temperature range at which a stable relaxor state exists is connected with electron tunneling from electron levels through the potential barrier generated by the superlattice of the TllnS2 crystal. The possibility of terahertz Bloch generator operation on the base of the super-structures of AIIIBIIICVI2 compoundshas been stated.
