In this talk,I will present our results of graphene study: understanding on graphene intercalation,and properties of folded and mis-oriented graphenes.With the availability of few-layer graphene,we shed new light on the mechanism of intercalation of graphite which is not possible before [1,2].Folded graphene sheets exhibit two-dimensional Dirac-like(single layer graphene-like)character of electronic states and with reduction of Fermi velocity [3].For applications in nano-electronic devices and energy harvesting,opening of the band gap is needed.On the other hand,many of the unique properties of graphene are accorded to that of single layer graphene(SLG).But it is very difficult to fabricate large single crystalline SLG samples for practical applications.It would be most desirable to modify few-layer graphene(FLG)samples so that they have similar properties as that of SLG.I will also present our results in modifying graphene for various applications,including applications in energy storage.
