Simple Fabrication of Mg2Si Thermoelectric Generator

Mg2Si polycrystals have been grown by heat treatment of bulk Si under Mg vapor. The structural property of the Mg 2Si has been investigated. The Mg 2Si shows n-type conduction. The impurity doping to obtain p-Mg 2Si was also demonstrated. In addition, simple fabrication procedure of Mg2Si thermoelectric generators has been developed.
