Snap-Through Instability of Graphene on Substrates

Li, Teng and Zhang, Zhao (2010) Snap-Through Instability of Graphene on Substrates. Nanoscale Research Letters, 5 (1). pp. 169-173.



We determine the graphene morphology regulated by substrates with herringbone and checkerboard surface corrugations. As the graphene–substrate interfacial bonding energy and the substrate surface roughness vary, the graphene morphology snaps between two distinct states: (1) closely conforming to the substrate and (2) remaining nearly flat on the substrate. Since the graphene morphology is strongly tied to the electronic properties of graphene, such a snap-through instability of graphene morphology can lead to desirable graphene electronic properties that could potentially enable graphene-based functional electronic components (e.g. nano-switches).
