The V-groove confines the anisotropic dewetting of Cu film to form ribbons. The influence mechanism of film thickness and annealing procedure on the confined dewetting, structural and morphological evolution has been investigated. Thus, the synthesized graphene ribbons by CVD have uniform width, regular edges and good crystallinity, and deliver obvious room-temperature PL emission.
