Strained MBE graphene grown on hBN flakes exfoliated on a sapphire substrate (carbon aggregates across the sapphire provide a conductive substrate/connection to graphene) recorded with the NuNano Spark 70 Pt probe. All images recorded with an Asylum Research Cypher S AFM under ambient conditions. A negative bias of -5mV was used for all images.
