Abstract

We investigate the thermoelectric properties of β-FeSi₂ using first principles electronic structure and Boltzmann transport calculations. We report a high thermopower for both p- and n-type β-FeSi₂ over a wide range of carrier concentration and in addition find the performance for n-type to be higher than for the p-type. Our results indicate that, depending upon temperature, a doping level of 3 × 10²⁰ to 2 × 10²¹ cm^-3 may optimize the thermoelectric performance.
