Journal Club for February 2017: Nanoscale buckling in 2D materials
Graphene as a typical two dimensional (2D) crystal membrane attracts tremendous interest. Geometrical distortion such as nanoscale buckling morphology is widely observed in these 2D materials and is crucial to modulating the electronic properties [1]. The calculated bending stiffness of graphene is found to be the same order as that of the lipid bilayer [2], therefore buckling instability may easily occur in graphene leading to non-planar configurations.
