Although Te-based TE materials usually exhibit better performance and hold the dominant market share, it is necessary to develop alternative materials to replace the rare and toxic Te.
The raw materials were milled for 5, 10 and 15 h whilst other parameters were kept constant.
Those free charge carriers reduce the resistivity of the semiconductor materials.
