Many Body Interactions on Lattice Dynamical Properties of Stanene, 2D Material

Abstract

The study of the lattice dynamical properties of materials, phenomenological models describe a complete and straight forward description of the phonon dispersion and phonon eigenvectors in whole Brillouin Zone (BZ) and can be easily applied to the calculation of phonon density of states, elastic constants , dielectric permittivity and other properties of solid .Adiabatic Bond Charge Model (ABCM) was originally developed by W. Weber for studying the lattice dynamics of tetrahedrally bonded bulk group IV Semiconductors such as Si, Ge,Sn and diamond. The result obtained from this model is good agreement with the experimental data for Stanene. We, at present find the lattice dynamical matrix and secular equations using Adiabatic Bond Charge Model. We hope that lattice dynamical properties of Stanene as a 2D material will be good fitted with experimental data.
