Lysko V. Physical methods and devices for the research into thermoelectric materials

The dissertation covers the development of physical methods to improve the accuracy of measurements of the thermoelectric material properties and the creation on their basis measuring devices for both scientific and industrial applications. New physical methods of improvement the measurement accuracy, obtained by technology of object-oriented computer simulation, are of theoretical value for creation of high-precision methods and equipment for measuring the thermoelectric material properties. High-precision measurement systems for research of the properties of thermoelectric materials were designed and developed, whose accuracy in determining of the thermoelectric figure of merit are 3 to 5 times higher than that of the well-known analogues, thus allowing their use for solving problems of improving the figure of merit of the thermoelectric materials. Equipment for quality control of thermoelectric materials during manufacturing of thermoelectric energy converters was designed and developed, the use of which improves the efficiency of thermoelectric modules by 8 to 15% and reduces the consumption of the thermoelectric material by ~ 10%.
