Near-field photocurrent nanoscopy on bare and encapsulated graphene

Near-field photocurrent nanoscopy on bare and encapsulated graphene

Graphene grain boundaries and charge inhomogeneities limit its electronic properties. Here the authors combine scanning near-field optical microscopy with electrical read-out to image these defects at the nanoscale under an encapsulation layer, and show that charges build up along the edges of the f...
