2 Jun 2013 | | Abstract: | Graphene is only one atom thick and becomes the ultimate thin film to explore
membrane physics and mechanics. Here we study hierarchy of graphene wrinkles
induced by thermal strain engineering and demonstrate that the wrinkling
hierarchy can be accounted for by the wrinklon theory. We derive an equation
explaining evolution of wrinkling wavelength with the distance to the edge y
observed in our experiment by considering both bending energy and stretching
energy of the graphene flakes. Our experiment and analysis indicate that the
prefactor k ~ 55 nm in the equation is only determined by the intrinsic
parameters of the graphene flakes. | | Source: | arXiv, 1306.0171 | | Services: | Forum | Review | PDF | Favorites | |
