Geometric analysis of the properties of germanene using Lifson–Wershel potential function

Abstract

Numerous experiments on graphene, which is a 2D carbon material with excellent mechanical and electrical properties, have been carried out in recent years. By recognizing the properties of graphene, the researchers focused on other two-dimensional materials. Several studies have been done on graphene, but other two-dimensional structures have not yet been studied extensively. In this work, Germanene’s simulation of molecular dynamics was performed and Germanene’s stress–strain curve was obtained. The mechanical properties of Germanene have been investigated by practicing the proposed method of structural molecular mechanics. The two-step procedure was followed, where, in first step with the aid of the relations governing the force field and the Lifson–Wershel potential function and structural mechanics relations, the coefficients for the BEAM elements were found, and a structural mechanics model for Germanene was proposed. Then, a germanene sheet with [Formula: see text] Ȧ was modeled and Young’s modulus of Germanene was obtained by molecular dynamics and proposed molecular mechanics methods.
