Heavily Doped p-Type PbSe with High Thermoelectric Performance: An Alternative for PbTe

Authors


Abstract

PbSe was expected to have a smaller bandgap and higher thermalconductivity than PbTe. Instead, these values are about the same at high temperature leading to comparable thermoelectric figure of merit, with zT> 1 achieved in heavily doped p-type PbSe.
