Basic scientific achievements Produced, for the first time, nano-films of the GaSe and investigated quantum size effects in the films. Developed technology to produce active compositions and investigated polarization processes, interphase interaction and heat physical effects in the piezoferroelectrics  and composites. On this basis, created different transducers. At high temperatures and pressure, structural phase transitions in the ferroelectric perovskites of PbTiO3, NaNbO3, BiMnO3 were studied. It was found that in PbTiO3 at T ≈ 720 K and P ≈ 2.5 GPA upon transition to a paraphrase, a sort of change occurs; a phase transition from the first to the second. In NaNbO3 with P pressure ≈ 1.6 GPa was observed to have a phase transition from an orthorhombic phase to a rhombohedral phase. For BiMnO3 the appendix of  high pressure causes essential reduction of critical temperature of phase transition from a monoclinic phase to an orthorhombic phase with a coefficient of pressure of dTC/dP = – 39 (1) K/GPA. Methods of neutron diffraction with high pressures of 5.4 GPA at room temperature and power dispersive x-ray diffraction with high pressures of 4 GPA in the range of temperatures of 300 – 400K - - The crystal structure of an anti-ferroelectric material of Pb2MgWO6 was also investigated. Temperature and pressure dependences of parameters, volume of an elementary cell and interatomic lengths of communication were received; coefficients of thermal expansion and modules of comprehensive compression for the antiferroelectric and paraelectric phases Pb2MgWO6 were calculated. Developed and produced PC based data acquisition system for recording, processing and visualization of experiments data.
