[摘要]：The electrical conductivity and structural properties of monolayer graphene (MLG) have been studied. MLG is fabricated from single-walled carbon nanotubes (SWCNTs) using high direct current pulse and microwave irradiation. Transformed MLG initially obtained from SWCNTs was not a stable planar structure because of its high surface energy. Therefore, they became stacked together to form the few-layer graphene structure. With the exfoliation process using an alkali metal, the stacked structure changes to a monolayer structure. A variety of characterizing techniques, such as a field emission scanning electron microscopy, high resolution transmission electron microscopy, high resolution Raman spectroscopy, and X-ray photoelectron spectroscopy were used for the analysis of MLG structures.
