Firstly, large area graphene (2 x 2 cm(2)) was prepared by chemical vapor deposition on Cu foils and then transferred onto SiO2 substrates by a transfer process. The Cu nanoparticles were collected on graphene/SiO2 by magnetron sputtering. The presence of graphene was verified by optical microscopy and Raman spectroscopy. The structure of graphene decorated with Cu nanoparticles was determined by scanning and transmission electron microscopy. The results show that the Cu nanoparticles acquire a cubic structure on grapheneeninfo:eu-repo/semantics/closedAccessCrystallographyCu nanoparticleCVDGas phaseGrapheneMagnetron sputteringCompositesSensorSheetChemical vapor depositionHigh resolution transmission electron microscopyMagnetron sputteringNanoparticlesScanning electron microscopySilicaSilicon compoundsSinteringSputteringSynthesis (chemical)Transmission electron microscopyGrapheneCu foilCu nano-particlesCubic structureGasphaseLarge-area grapheneScanning and transmission electron microscopySIMPLE methodTransfer processArticle0004149833000062-s2.0-850334530785211CrystallographyRaman Spectroscopy; Graphene Oxide; Graphite
