Effect of Many Body Interactions on Phonon Group Velocities of Stanene

Two-dimensional (2D) materials are one of the most active areas of nanomaterials research due to their potential for integration into next-generation electronic and energy conversion devices. 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 group velocities is needed for complete theoretical analysis of thermal energy transportandthermal conductivity of Stanene. The general three dimensional continuum model of phonons in two dimensional materials is developed for the theoretical prediction of the important thermal properties. The acoustical and optical contributions to the phonon group velocities are evaluated within the framework of Bond Charge Model. We, at present find the Phonon group velocities along symmetry directions using Adiabatic Bond Charge Model with the help of PYTHON Program. We hope that phonon group velocities along Г‒M of Stanene, 2D materials will have reasonably similar result obtained by other researchers.
