While graphene is atomically thin, it has a strong influence on the surface potential when it is transferred on a metal film. In this study, we investigated the charge transfer between the noble metal and the transition metal nitride (Au and ZrN) by the kelvin probe force microscopy (KPFM) and the spectroscopic ellipsometry. This work can be developed in graphene-plasmonics hybrid structures.
