1 Introduction Graphene ribbon self-assembly under ambient conditions at near macroscopic scales is an unexpected phenomenon ultimately emerging from a tendency to reduce the high surface-to-volume ratio intrinsic to 2D materials.[1-5] This behavior, for which we introduce the term “auto-kirigami” (AK) here, occurs by the combined spontaneous sliding and tearing of folded, incommensurately stacked graphene, providing a novel platform for studying 2D material nanomechanics and phenomena like...
