Graphene placed on a boron nitride (BN) substrate has been shown to result in increased mobility and improved Quantum Hall measurements. It is therefore of great interest to understand how BN substrates differently influence graphene compared to more standard Silicon oxide substrates. I will present new scanning tunneling microscopy measurements of graphene placed on a BN substrate. Differences in the local behavior of graphene on a BN substrate versus a Silicon oxide substrate will be discussed.
