Information × Registration Number 0211U006642, 0109U007537 , R & D reports Title The technology of thermoelectric materials based on lead telluride for HIGH cascading modules popup.stage_title Head Freik Dmytro Myhaylovych, Registration Date 02-03-2011 Organization Precarpathian university named after Vassyl Stefanyk popup.description2 The technology and designed the installation for the production of briquettes thermoelectric material developed and implemented a new method of studying the thermoelectric parameters of semiconductor materials in a wide temperature range (77-1000) K, the influence of technological conditions of preparation of thermoelectric material on its properties. The method of thermodynamic potentials described defect in crystals of Lead Telluride dvotemperaturnomu annealing in a pair of tellurium. Crystalloquasichemical formula for n-PbTe crystals by the interaction of tellurium with regard dysproportsionuvannya charge state of vacancies in cation sublattice and interstitial Pb. The influence of charge state and type of dominant defects in the implementation of thermodynamic n-p-transition in nonstoichiometric Lead Telluride. Methods krystalokvazihimiyi Mechanisms doping cobalt and nickel of n-and p-PbTe. Established that at substitution octahedral cavities (OP) and at rooting in tetrahedral cavities (TP) packed Te atoms lead telluride crystal lattice transition elements Co and Ni exhibit donor properties. Shown that the results are confirmed by comparing krystalokvazihimiyi ion (atomic, covalent) radii and the size of OP and TP. An analysis of defective crystalquasychemical subsystem for Lead Telluride nonstoichiometric n-and p-type conduction stanum telluride and solid solutions Pb1-xSnxTe based on p-PbTe. Determined depending on the concentration of point defects for Pb1-xSnxTe based on p-PbTe subject dysproportsionuvannya charge state cationic vacancies of staff. Established that the dominant defects in this case is two-and chotyryzaryadni metal vacancies. Based on experimental studies of thermoelectric materials based on Lead Telluride (PbTe: Pb (Te), PbTe: Ni (Bi), PbSnTe) and theoretical calculations using the methods of thermodynamic potentials and krystalokvazihimiyi The optimum technological parameters of synthesis of thermoelectric material and briquetting.
