Essay

SnTe crystals and films and SnTe/PbTe superlattices. Studying influence of defects on phase transitions in non-stoichiometric systems. Methods of research are X-ray diffractometry, dilatometry, electron microscopy, measurements of galvanomagnetic and thermal properties. Complex studying of ferroelectric phase transition was carried out. New phase transitions in SnTe with high concentration of non-stoichiometric defects, which are believed to be connected with ordering in defect subsystem were detected. Superconductivity was revealed in strained superlattices SnTe/PbTe. Field of application is controlling properties of materials for thermo-and photoconverters, detectors of IR-radiation.
