Calculation of Thermoelectric Properties of Doped SrTiO3

Abstract

Thermoelectric properties of cubic perovskite SrTiO3 have been investigated. The energy band structures are calculated using the total energy plane-wave pseudopotential method within the local density approximation (LDA) and generalized gradient approximation (GGA). The calculated energy band structures are then used in combination with Boltzmann transport equation to calculate the thermoelectric parameters of doped SrTiO3 especially seebeck coefficient, electrical conductivity and electronic thermal conductivity.
