Variation in elastic constants of plumbene with sample size and temperature estimated using bending and oscillation approaches: A Molecular dynamics simulation study

Two-dimensional (2D) nanomaterials, now days are attracting researchers round the globe for their irreconcilable structure and outstanding properties. Plumbene, referred as the cousin of graphene is the single-layered, hexagonally arranged atomic structure of lead. Previously bending and oscillation modeling were implemented to evaluate elastic constants of plumbene. We have studied the effect of increasing temperature and sample size on plumbene using the same loading methods. To perform our molecular dynamics (MD) simulation study a plumbene sheet is designed adopting multi-scale modeling. For the purpose of parroting an unfathomable perspective of elastic constants of the material for potent utilization in technological fields, under inconsistent loading situations scrutinization of plumbene sheets are overdone by molecular dynamics (MD) simulation. Current impetrated practices will rav experimental wriggle of designing plumbene sheets with meticulous elastic constants for coveted applications. Earlier Young's modulus (E) of plumbene is estimated using bending and oscillation modeling of plumbene under variable loading conditions. Here, we have studied variation of elastic constants {i.e. Young's modulus (E), Modulus of rigidity (G) and Bulk modulus (K)} of plumbene under the same loading conditions (i.e. bending and oscillation) with change in sample size and temperature using nonequilibrium molecular dynamics (NEMD) simulation technique.
