Abstract

We study formation and properties of graphene grown on diamond films with a prospect for large area deposition and devices of graphene. Nanocrystalline diamond thin films (grain size ~ 200 nm) are coated with a thin Ni layer (nominal thickness ~ 20 nm) and heated to 900°C in a forming gas atmosphere (H2/Ar) to initiate a thermally driven catalytic transformation of the diamond surface into graphene by a reaction of Ni with carbon. The samples are cleaned from residual Ni after the catalytic transformation. We employ scanning electron microscopy, Raman micro-spectroscopy, and Kelvin probe force microscopy showing how diamond and grain boundaries influence the graphene growth as well as graphene material, structural, and electronic properties.
