Thermodynamic and elastic properties of arsenic chalcogenides

The enthalpy and specific heat capacity of lead chalcogenides PbS, PbSe, and PbTe were measured experimentally. The isobaric specific heat capacity c p and adiabatic bulk modulus κ s were determined for solid and liquid states. The isothermal bulk modulus κ T , Gruneisen parameter γ, sound diffusion velocity u s , and isochoric specific heat capacity c v were calculated as functions of temperature
