Abstract Scope |
Present work involves a study on the surface crystallographic texture of Cu rich Cu-Ni alloy substrates and the effect of substrate texture on the quality of graphene grown on differently textured Cu-Ni alloy foils. Cu and Ni are the commonly used substrates for graphene growth to produce mono- and few layer- graphene, respectively. In present work, Cu-Ni alloy substrates were selected to control the number of layers of graphene. Cu rich Cu-Ni alloy buttons of various compositions were prepared by vacuum arc melting process. Cu-Ni alloy buttons were rolled and annealed to generate different crystallographic texture in Cu-Ni alloy substrates. Graphene was grown on annealed Cu-Ni alloy foils by CVD process to understand the effect of substrate texture on the graphene growth. The substrate textures were studied by XRD texture goniometer and EBSD (electron back scattered diffraction), whereas quality of graphene was assessed by Raman spectroscopy. |
