Nanoscale graphene sheets folded into atomic crêpes
Atom-thick sheets stacked with precise twist angle and tubular edge could be made into quantum nanomachines
Tiny graphene sheets only a single atom thick have been folded into nanosized crêpes that could eventually be made into molecular machine parts. This is the first time researchers have been able to only fine-tune the graphene sheets’ twist angle – and thereby their electronic properties – but also create a tubular edge.
