Raman spectroscopic investigation of graphene: defects and stacking geometry

摘要/Abstract:
Raman spectroscopy has been widely used to investigate the properties of graphene, including determining the layer numbers, probing charge impurities, defects, edge structures, strain and electronic structures. In this talk, we will focus on the studies of defects and stacking geometry in graphene and graphene layers by Raman spectroscopy. There are different amount and types of defects in graphene that either presented intrinsically or introduced externally. Such defects could be investigated by Raman spectroscopy and are found to play important roles in the properties of graphene, e.g. electronic band structures, photoresponse and thermal transport properties. We will also present results on the study of stacking geometry in graphene layers, i.e. twisted bilayer graphene (TBG), by Raman spectroscopy. The electronic coupling between the two graphene layers could significantly affects the band structures of TBG. Different Raman parameters including intensity, width, and position of G and 2D peaks can be used to distinguish TBG with different twist angles. The above results demonstrate that Raman spectroscopy is a versatile tool to probe the properties of graphene and/or other two dimensional materials.
