Definitely the Charge carrier scattering mechanisms for lead chalkogenides crystals and films with electronic conductivity in the wide range of temperatures and concentrations and their influence on the kinetic properties of material is set. The influencing a kind and charge states of own atomic defects in the crystals and films compounds bases on AIVBVI on the electronic processes is explored, that gave possibility to define technological conditions of the material growing with the beforehand set properties. On the basis of theoretical computation of basic thermo-electric parameters of lead chalkogenides crystals taking into account features of analytical type of law of dispersion and realization of dominant carrier scattering mechanisms for optimum thermo-electric parameters of lead chalkogenides crystals are definite for their forecast use in the electronics devices. It is set, that the high valuesof the thermo-electric quality (Z) exist in areas of low concentrations of transmitters in case of prevailing scattering on the vacancies. It is shown, that by influence on the prevailing machineries of dispersion (by strengthening that or other type of dispersion, through, for example, alloying or creation of solid solutions) it is possible to optimize basic thermo-electric parameters. Thermo-electric parameters of solid solutions are explored on the basis of lead telluride. Technologies are developed for the receipt of materials with the set type of conductivity and high thermo-electric parameters for their forecast use in the device structures of microelectronic and thermo-electric transformers of energy, a novelty of which was protected by patents of Ukraine.
