Graphene has attracted much attention since its first discovery in 2004. Various approaches have been proposed to control its physical and electronic properties. Here, it is reported that graphene‐based intercalation is an efficient method to modify the electronic properties of few‐layer graphene (FLG). FeCl3 intercalated FLGs are successfully prepared by the two‐zone vapor transport method. This...
In this paper, the 1 + 1 layer folded graphene sheets that deviate from Bernal stacking are successfully fabricated and their electronic and optical structures are investigated by Raman and contrast spectroscopy. Significant blueshift of the single Lorentzian 2D band of folded graphene compared to that of single layer graphene (SLG) is observed, as shown in Fig. 1. This is attributed to SLG-like electronic...
Graphene has many unique properties that make it an ideal material for fundamental studies as well as for potential applications. Here we review recent results on the Raman spectroscopy and imaging of graphene. We show that Raman spectroscopy and imaging can be used as a quick and unambiguous method to determine the number of graphene layers. The strong Raman signal of single layer graphene compared...
