摘要: The thermodynamic properties of ZnSe are obtained by using quasi-harmonic Debye model embedded in Gibbs-code for pressure range 0-10 GPa and for temperature range 0-1000 K. Helmholtz free energy, internal energy, entropy, Debye temperature, and specific heat are calculated. The thermal expansion coefficient along with Grüneisen parameter are also calculated at room temperature for the pressure range. It is found that internal energy is pressure dependent at low temperature, whereas entropy and Helmholtz free energy are pressure sensitive at high temperature. At ambient conditions, the obtained results are found to be in close agreement to available theoretical and experimental data.
