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

In this work, the thermoelectric properties of p- and n-type β-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,...
