Abstract

Graphene films were grown by chemical vapor deposition on Cu foil. The obtained samples were characterized by Raman spectroscopy, ellipsometry, X-ray photoelectron spectroscopy and electron back-scatter diffraction. We discuss the time-dependent changes in the samples, estimate the thickness of emerging CuO beneath the graphene and check the orientation-dependent affinity to oxidation of distinct Cu grains, which also governs the manner in which the initial strong Cu-graphene coupling and strain in the graphene lattice is released. Effects of electropolishing on the quality and the Raman response of the grown graphene layers are studied by microtexture polarization analysis. The obtained data are compared with the Raman signal of graphene after transfer on glass substrate revealing the complex interaction of graphene with the Cu substrate.

摘要

通过化学气相沉积法在铜箔上生长石墨烯薄膜。对所得样品进行拉曼光谱、椭偏仪、X射线光电子能谱和电子背散射衍射表征。我们讨论了样品随时间的变化，估计了石墨烯下方新出现的氧化铜的厚度，并检查了不同铜晶粒氧化的取向依赖性亲和力，这也决定了石墨烯晶格中初始强铜-石墨烯耦合和应变的释放方式。通过微观织构极化分析研究了电化学抛光对生长的石墨烯层质量和拉曼响应的影响。将所得数据与转移到玻璃基板上的石墨烯的拉曼信号进行比较，揭示了石墨烯与铜基板的复杂相互作用。
