Report on research work: 145 pages, 93 figs, 6 tables, 134 references. CONTACT RESISTANCE, MEASUREMENT, ACCURACY, THERMOELECTRIC ENERGY CONVERTERS, PROBE METHOD, ABSOLUTE METHOD, MINIATURIZATION. The object of research is methods and equipment for determining the contact resistance of “metal-thermoelectric material” structures for thermoelectric energy converters. The purpose of the work is to develop high-precision methods and equipment for determining the contact resistances of "metal-thermoelectric material" structures, necessary for the comprehensive optimization of such transient contact structures in thermoelectric energy converters and the creation of technologies for their production. Research methods – methods of mathematical physics; methods of computer object-oriented simulation of heat and electricity transfer processes, in particular, in thermoelectric media; experimental methods of thermal physics; error theory. As a result of the work based on a detailed analysis of physical models and multifactor computer optimization of measurement processes and the design of measuring equipment, a device was developed and manufactured to determine the electrical contact resistance of "metal - thermoelectric material" structures with a value of 10-5 - 10-8 Ohm∙cm2. A method for determining the thermal contact resistance of such structures was developed based on a comprehensive absolute method for measuring the parameters of thermoelectric materials. The design of the "ALTEC-10001" equipment was improved to implement the proposed method. A series of experimental studies of the developed equipment was conducted. The created unique equipment for measuring the contact resistance of the "thermoelectric material - metal" structures exceeds world analogues in its characteristics.
