Enhancement in thermoelectric performance of n-type Pb-deficit Pb-Sb-Te alloys

PbTe based materials are well known for their high performance thermoelectric properties. Here, a systematic study of thermoelectric transport properties of n-type Pb-deficit Pb0.98-xSbxTe alloys with carrier concentrations in the range of ∼10−19 cm−3 is presented from room temperature to 623 K. A m...
