Overview on high potential material for Thermoelectric and their structure

Abstract

This report will review the most promising material for thermoelectric application (thermoelectric refrigerator and thermoelectric generator). Here we are concerned on the material selection with emphasizing on their structure in order to achieve high thermoelectric figure of merit. Four kinds of material structure with Phonon Glass Electron Crystal (PGEC) approach are highlighted here, those are skutterudite structure, clathrate structure, half – Heusler structure and chalcogenide phase. They are established materials for thermoelectric and intensively studied by many researchers related to thermoelectric area.
