Since Dr.Iijima reported his observation of tubular carbon under transmission electron microscopy(TEM)in 1991,carbon nanotubes(CNTs)have attracted intensive attention.A single-walled CNT(SWNT)is a seamless cylinder formed by rolling a piece of graphene,the honeycombstructured sp2 carbon.This unique structure endows SWNTs
