Fluorine doping for improved thermoelectric properties of spark plasma sintered bismuth telluride

Bismuth-telluride (Bi2Te3) is considered to have the best thermoelectric properties at room temperature (ca. 300 K). Thus, synthesis and improvement of Bi2Te3 and its derivatives quickly and cost-effectively at favorite temperatures are of interests. Recently, doping fluorine (F) into electronic materials (e.g., FTO) has gained attention; however, it is not applied to Bi2Te3 till now. Here, our synthesis of F-doped Bi2Te3 for thermoelectric...
