Many-Body Interactions on Phonon Properties of Stanene

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