Applied Physics and Mathematics Annotation << Back COMPARISON OF THERMOELECTRIC AND THERMAL PROPERTIES OF COARSE-GRAINED AND NANO-GRAINED CU1.96TE SEMICONDUCTOR M.KH. BALAPANOV, R.KH. ISHEMBETOV, YU.KH. YULAEVA, R.A. YAKSHIBAEV, K.A. KUTERBEKOV, M.M. KUBENOVA This article presents the results of a comparison of electronic conductivity, coefficient of electronic thermo-e.m.f. and the total thermal conductivity of coarse-grained and nano-grained copper telluride samples in the temperature range 300–675 K. The thermoelectric figure of merit ZT increases from 0.12 to 0.54 with a decrease in grain size from 50 μm to 50 nm. Keywords: electrical conductivity, thermo-emf., thermal conductivity, thermoelectrics, copper telluride. DOI: 10.25791/pfim.05.2020.1171 Pp. 03-08.
