Abstract

Theoretical modeling of ZT of (111) and (001) oriented PbTe/Pb1-xEuxTe multiple-quantum-wells (MQWs) is carried out assuming parabolic energy bands and the constant relaxation time approximation. The model calculation for the (111) oriented MQWs is compared with the recently obtained experimental results for the Seebeck coefficient and the Hall carrier concentration. The thermoelectric properties for (001) oriented PbTe MQWs are expected to have even better thermoelectric properties than the (111) oriented PbTe MQWs.
