COMPOSITE THERMOELECTRIC MATERIALS WITH NANOINCLUSION: CURRENT STATUS AND OUTLOOK (REVIEW)

A review of works devoted to composites thermoelectrics, operating in different temperature intervals: room (300-400) K (Bi2 Te3 , Bi2 Te3 -Sb2 Te3 ); medium temperature (500-700) K (PbTe, Mg2 Si Last, skuterudyty, Half-Heusler compounds, clathrates), high temperature (900-1500) K (Si1-xGex , La3-xTe4 ). Emphasis on the technological features of the synthesis of compounds and preparation of thermoelectric structures, analysis of their structure and termoelektryrsnoyi merit. It is shown that the introduction of nanoparticles within the scope of the basic material leads to a significant improvement of thermoelectric properties. The basic strategy for further progress in the thermoelectric material.
