ABSTRACT
Thermoelectric technology, harvesting electric power directly from heat, is a promising environmentally friendly means of energy saving and power generation. According to the optimal working temperature, thermoelectric materials can be sorted into three groups [1,2]. At low temperatures (<400 K), typical materials are Bi2Te3 based [3-5] and CsBi4Te6 [6];
