Defect-guided wrinkling in graphene.

Highlights: [•] We present a conceptual design of defect-guided wrinkling controller in graphene. [•] The line defect may be regarded as a controller embedded in pristine graphene. [•] The graphene wrinkling may be controlled by tuning the defect angle. [•] The tuning is realized by the buckling and energy release of the defected structure. [•] The wrinkling controller is benefit to the nano-mechanical systems and graphene composite. [ABSTRACT FROM AUTHOR]
