英文摘要 | A simple pseudopotential model is used for the calculation of the temperature dependence of the lattice mechanical properties which depend on the phonon density of states, such as the lattice heat capacity CV , the Debye temperature θD, the harmonic contribution to the free energy, the thermal pressure, the isothermal bulk modulus corrected to the fourth order and volume, the thermal expansion coefficient β, βBTΩ/3Nk□, the Debye-Waller factor, the mean-square displacement, the Debye-Waller temperature parameter, and the X-ray characteristic temperature θM of Cu, Ag, Au, Ni, Pd, Pt, Rh, and Ir. The contribution of d-like electrons is taken into account by introducing a repulsive short range Born-Mayerlike term. The theoretical results are compared with the experimental findings wherever possible. A good agreement between the theoretical investigations and the experimental findings demonstrates the capability of our model potential for successfully explaining the lattice vibrations and the related properties of some cubic transition metals. |
