Significant efforts are being invested in investigation of graphene, as well as its nanopatterning and shaping, owing to its promising properties. Here we present a study of hexagonal graphene flakes, deposited on a copper foil by chemical vapor deposition. In particular we have exploited a Near-Field Scanning Microwave Microscope, and investigated the impact of the microwave power on the sample. From preliminary data, we found the possibility of inducing a localized destruction of the graphene by means of the near-field microwave probe. We exploited this effect to create a recognizable pattern on a flake. A discussion of the roles of concurrent physical phenomena is also presented.

Abstract
Significant efforts are being invested in investigation of graphene, as well as its nanopatterning and shaping, owing to its promising properties. Here we present a study of hexagonal graphene flakes, deposited on a copper foil by chemical vapor deposition. In particular we have exploited a Near-Field Scanning Microwave Microscope, and investigated the impact of the microwave power on the sample. From preliminary data, we found the possibility of inducing a localized destruction of the graphene by means of the near-field microwave probe. We exploited this effect to create a recognizable pattern on a flake. A discussion of the roles of concurrent physical phenomena is also presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
