Analysis of Anharmonic Properties of Some Partially Covalent Crystals

Abstract: The anharmonic properties of silver, thallium, and copper halides are analysed by means of a new interionic potential model which incorporates the effects of the long-range Coulomb and threebody interactions and the short-range van der Waals (vdn') attraction and overlap repulsion extended up to the second-neighbour ions. The model potential is applied to investigate the thirdorder elastic constants and the pressure derivatives of second-order elastic constants of the crystals. Additively some thermodynamic an… Show more
