Direct growth of graphene pad on exfoliated hexagonal boron nitride surface

摘要

A direct and metal layer-free growth of flat graphene pads on exfoliated hexagonal boron nitride substrate (h-BN) are demonstrated by atmospheric chemical vapour deposition (CVD) process. Round shape with high flatness graphene pads are grown in high yield (~95%) with a pad thickness of ~0.5 nm and homogenous diameter.
