| Abstract: | We prepared trilayer graphene by the means of micromechanical cleavage.Trilayer graphene were intercalated into stage-1 anhydrous ferric chloride(FeCl3) and potassium(K) intercalation compounds using a two-zone vapour transport method.The 2D band of trilayer graphenes has a distinct lineshape,which can be used as a fingerprint for characterizing trilayer graphenes.The Raman spectra of stage-1 trilayer graphene intercalation compounds indicate that each graphene layer between intercalant layers behaves as a decoupled heavily doped monolayer graphene.The multilayer graphene intercalation compounds with nano-scale thickness have great potential for investigations of fundamental physics and for their applications in electronics and photonics. |
