High‐Temperature Thermoelectric Properties of Sn‐Doped β‐As2Te3

Thermoelectric energy conversion is a versatile and an all-solidstate technology that can be used either in cooling systems (Peltier effect) or in electrical power generators (Seebeck effect). Because thermoelectric generators convert directly temperature differences into electrical power, this technology, thanks to its reliability, long lifetime, and vibration-free character, has been successfully used for decades for powering deep space missions. Thermoelectric generators may be equally suitable for waste-heat recovery from automotive exhaust systems or various industrial processes. Near room temperature, Peltier coolers are applied as solid-state heat pumps for cooling electronic devices, for instance. [ 1,2 ] The active parts of thermoelectric devices are composed of n - and p -type materials whose intrinsic transport properties govern the overall conversion effi ciency. The potential of a given material for thermoelectric applications is quantitatively expressed by the dimensionless fi gure of merit ZT defi ned as α ρ κ κ κ κ
