层状结构中的薄膜与2D片:石墨烯和2D金属片

Thin films versus 2D sheets in layered structures: graphene and 2D metallic sheets

Bo E. Sernelius

摘要:

我们研究了两个介质之间的界面分离的一个严格的二维片。我们展示了如何振幅反射系数可以建模的接口,其中的2D片已被替换为一个小的,但有限厚度的膜。我们给出了薄膜的三维介电函数和薄片的二维介电函数之间的关系。我们选择石墨烯和2D金属片作为说明性例子。这种方法在处理非平面结构中的石墨烯或石墨烯类薄片时非常有用

英文摘要:

We study an interface between two media separated by a strictly 2D sheet. We show how the amplitude reflection coefficient can be modeled by that for an interface where the 2D sheet has been replaced by a film of small but finite thickness. We give the relationship between the 3D dielectric function of the thin film and the 2D dielectric function of the sheet. We choose graphene and a 2D metallic sheet as illustrative examples. This approach turns out to be very useful when treating graphene or graphene like sheets in non-planar structures
