Abstract:Thermoelectric materials should be highly efficient and mechanically robust to satisfy the requirements of engineering applications. Herein, an integrated optimization strategy to improve both the thermoelectric performance and mechanical strength of SnTe is proposed. First, grain boundary engineering is applied to SnTe via MgB2 doping. The decomposition of MgB2 results in the Mg‐substituted SnTe solid solution and a special “core–shell” structure of Mg‐B compounds coated SnTe grain remarkably reducing the lat… Show more
SnTe based compounds have long been considered to be competitive in thermoelectric power generation. However, its intrinsically high hole concentration due to Sn vacancies and inferior band structure featured by...
