Effects of doping elements in ¢-FeSi2 prepared utilizing cast iron scrap chips

In this work, the thermoelectric properties of p- and n-type ¢-FeSi2, prepared utilizing cast iron scrap chips, have been characterized by measuring the Seebeck coefﬁcient, electrical conductivity and thermal conductivity at temperatures ranging from room temperatures to 800°C. In a previous study,...
