Defect-free mixed mono- and bi-layer graphene synthesized from refined palm oil by thermal chemical vapor deposition

Growth of defect-free large-area mixed mono-and bi-layer graphene using refined cooking palm oil on nickel (Ni) via thermal chemical vapor deposition was demonstrated for the first time. Small surface roughness of Ni substrate was obtained by annealing in hydrogen (H2) ambient. Small surface roughne...
