Many-Body Interactions on Phonon Properties of Stanene

Abstract

Novel properties are observed to arise at 2d level, which is typically absent in their bulk counterparts. Graphene, the most widely studied 2D material. Recently, the other 2D group-IV materials, silicene, germanene and stanene, have been realized by epitaxial growth on substrates and attracted tremendous interest due to their extraordinary properties. The discovery of stanene, a buckled monolayer of tin atoms arranged in a 2D honeycomb lattice, has explored enormous research interest in the materials in the two-dimensional (2D) realm. Stanene exhibit ductile nature and hence could be easily incorporated with existing technology in semiconductor industry on substrates in comparison to Graphene. the systematic investigation of phonon properties for stanene is needed. The general three dimensional continuum model of phonons in two dimensional materials is developed. At present, our research group find the lattice dynamical matrix and secular equations with solutions, phonon dispersion curve and Phonon density of states using Adiabatic Bond Charge Model with the help of MATLAB. We hope that phonon properties of Stanene will be good fitted with experimental data.
