Abstract: In applying the elastic shell models to monolayer or fewlayer twodimensional (2D) materials, an effective thickness has to be defined to capture their tensile and outofplane mechanical behaviors. This thinshell thickness ...

Abstract: Topological defects (TDs) arise in the growth process of twodimensional (2D) materials, as well as aftergrowth heat treatment or irradiation. Our atomistic simulation results show that their mechanical modulation of material ...

Abstract: Silicene is a twodimensional (2D) allotrope of silicon with a rippled or corrugated honeycomb structure in analogy to graphene. Its semiconducting properties make it attractive for developing future nanoelectronic devices. ...

Abstract: We explore here the structural stability and fracture of supported graphene sheets under pressure loadings normal to the sheets by performing molecular dynamics simulations. The results show that, in absence of defects, ...
