Is the alumino-boron carbide Al3BC a promising thermoelectric material? A computational exploration
Abstract : The structural, electronic and vibrational properties of the ternary borocarbide Al3BC are studied using first principles calculations in order to evaluate its potential use for thermoelectric applications. A fuller description of its crystal structure was achieved on the basis of an orthorhombic unit cell, twice larger than the previously reported experimental one. Using a semi-classical approach, the electronic transport properties were studied, and a high power factor is expected for this compound. A high thermal conductivity is foreseen on the basis of phonon calculations, suggesting that further developments aiming at its reduction would be necessary for thermoelectric applications. © 2020 Elsevier Masson SAS
