摘要
We investigate the thermodynamic properties of Pbca-BN, which has been carried out with the quasi-harmonic Debye model. The quasi-harmonic Debye model, using a set of total energy versus molar volume obtained with the first-principles calculations, is applicable to the study of the thermal and vibrational effects. The heat capacity, isothermal bulk modulus, Griineisen parameter, entropy, molar Gibbs free energy, Debye temperature, and thermal expansion dependence on the temperature and pressure are obtained in the whole pressure range from 0 to 90 GPa and a temperature ranging from 0 to 1000 K by calculation in this paper.
