Abstract

     The thermoelectric material based on the SiGe alloy has been used for several decades as the main element of TEG in space flights [1]. Recently, μTEGs have also been created on the basis of SiGe [2]. This thermoelectric is characterized by high efficiency (i.e. ZT~1) [3].

     The electronic quality factor (BE) and universal electrical conductivity (σ') are important characteristics of thermoelectric materials [4]. In particular, BE performs scaling of thermoelectric quantities.
