Computer calculations of the temperature dependencies of molar heat capacity at constant volume CV and pressure Cp were performed for cluster models of sphalerite-type zinc chalcogenide crystals, applying the density functional theory (DFT), using the approximation of the hybrid valence basis set B3LYP. The calculated values were compared with experimental results.
