It was shown that the electron processes in such crystals are fast-acting and occur in sub-nanosecond range. The nature of electron traps was determined. For the first time the photo-EMF effect (holographic current) was investigated and micromechanism of holographic current appearance in СdTe:V taking into account real defect structure of the crystal was established. Complex optical and photoelectric investigations of Sn2P2S6 crystals and Pb1-xCdxI2 solid solutions were carried out. The diagram of the defect levels energy and band-to-band electron transitions in Sn2P2S6 crystals was suggested. The NQR spectra studies showed that in Pb1-xCdxI2 crystals there appear intralayer mechanic tensions due to different values of Pb2+ and Cd2+ ionic radii and island heterophase structure is formed due to the formation of PbI2 and CdI2 within a layer.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
