We obtained atomically clean graphene membrane by annealing free-standing graphene in ultra-high vacuum transmission electron microscopy (UHV-TEM). Copper (Cu) nanoparticles formed by in-situ e-beam deposition of Cu atoms onto the clean graphene surface. The interaction between individual metal nanoparticles and this exceptional clean suspended graphene membrane was demonstrated by the stabilization and uniform distribution of Cu nanoparticles on the graphene surface. After carefully analyzing, we report the individual metal nanoparticle induced local strain field on the graphene membrane. The result is crucial to understand the structural effect and charge transfer between graphene and Cu nanoparticles.
