Prediction of Room Temperature High Thermoelectric Performance in n-type La(Ru,Rh)4Sb12
Marco Fornari, David J. Singh
Abstract
First principles calculations are used to investigate the band structure and the transport related properties of unfilled and filled 4d skutterudite antimonides. The calculations show that, while RhSb3 and p-type La(Rh,Ru)4Sb12 are unfavorable for thermoelectric application, n-type La(Rh,Ru)4Sb12 is very likely a high figure of merit thermoelectric material in the important temperature range 150-300 K.
