Published in PRB (Editor's Suggestion): Out-of-plane corrugations in graphene heterostructures


Even when sandwiched between atomically flat hBN crystals, surprisingly, graphene still exhibits ripples, even in absence of bubbles. These out-of-plane corrugations reduce mobility and suppress weak localization in an in-plane magnetic field. This effect allows extraction of the corrugation volume, in very good agreement with AFM measurements. Editor's Suggestion
