Progress on Mg_2Si thermoelectric materials

摘要

Mg_2Si which is composed of less toxic and naturally abundant elements, has attracted more attention for its potential application to thermoelectric devices. In this paper, the basic performance and preparation technique of Mg_2Si thermoelectric materials are introduced, reviewed the current research progress of Mg_2Si thermoelectricity. And the paper points out the existing problems and the trend of study in the future.
