Abstract

To realize the potential of graphene in nanoelectronic devices, large area of graphene sheets with high quality are desirable. Here, we have proposed a new method to weld the reduced graphene oxide (rGO) together by efficient coupling reaction, leading to the lateral size increased. Both crystallinity and electrical conductivity of the welded rGO were significantly improved. Furthermore, the reaction mechanism is studied by Raman, TEM, XPS spectra, optical transmittance, and square resistance measurements. Our technique can product high-quality graphene for fabricating graphene devices.
