Heat Capacity and Thermodynamic Properties of Lead Selenide and Lead Telluride

摘要

Given that the heat capacities of PbSe and PbTe had been previously measured only below 240 and 260 K, respectively, we evaluated unreported heat capacity values up to 298.15 K. The low- and high-temperature heat capacity data were matched, and the thermodynamic functions of PbSe and PbTe were calculated from 298.15 K to temperatures close to their melting points.
