Despite theoretical predictions that graphene should be impermeable to all gases, practical experiments on sealed graphene nanodrums show small leak rates. Thus far, the exact mechanism for this permeation has remained unclear, because different potential leakage pathways have not been studied separately. Here, we demonstrate a sealing method that consists of depositing SiO<sub>2</sub> across the edge of suspended multilayer graphene flakes using electron beam-induced deposition. By sealing, lea ...[more]
