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 60 × 70 ? was modeled and Young's modulus of Germanene was obtained by molecular dynamics and proposed molecular mechanics methods. © 2020 World Scientific Publishing Company.
