摘要:

我们分析了单个石墨烯层和SiO $_2$衬底以及可能存在于其环境中的其他材料之间的静电相互作用。我们得到的领先效应产生的极性模式在SiO $_2$表面,和水分子,这可能会形成层之间的石墨烯片和衬底。相互作用的强度意味着石墨烯以大于几个晶格间距的距离被钉扎到衬底上。石墨烯纳米机电系统的影响,和石墨烯和STM尖端之间的相互作用也被认为是。

英文摘要:

We analyze the electrostatic interactions between a single graphene layer and a SiO$_2$ susbtrate, and other materials which may exist in its environment. We obtain that the leading effects arise from the polar modes at the SiO$_2$ surface, and water molecules, which may form layers between the graphene sheet and the substrate. The strength of the interactions implies that graphene is pinned to the substrate at distances greater than a few lattice spacings. The implications for graphene nanoelectromechanical systems, and for the interaction between graphene and a STM tip are also considered.
