Edge Control of Graphene Domains Grown on Hexagonal Boron Nitride

Abstract

Edge structure of graphene has a significant influence on its electronic properties. However, control over the edge structure of graphene domains on insulating substrates is still challenging. Here we demonstrate edge control of graphene domains on hexagonal boron nitride (h-BN) by modifying ratio of working-gases. Edge directions were determined with the help of both moiré pattern and atomic-resolution image obtained via atomic force microscopy measurement. It is believed that the variation on graphene edges mainly attributes to different growth rates of armchair and zigzag edges. This work demonstrated here points out a potential approach to fabricate graphene ribbons on h-BN.
