摘要:

石墨烯在电子器件中的应用需要大规模外延生长。然而,衬底的存在通常显著降低了载流子迁移率。我们表明,它是可能的解耦的部分sp3杂化的第一石墨层上形成的Si-终止面的碳化硅从衬底上的金插层,导致一个完全sp2杂化的石墨烯层具有改善的电子性能。

英文摘要:

The application of graphene in electronic devices requires large scale epitaxial growth. The presence of the substrate, however, usually reduces the charge carrier mobility considerably. We show that it is possible to decouple the partially sp3-hybridized first graphitic layer formed on the Si-terminated face of silicon carbide from the substrate by gold intercalation, leading to a completely sp2-hybridized graphene layer with improved electronic properties.
