Abstract
A novel approach utilizing current-assisted CO2 laser irradiation was used to join two monolayer graphene flakes. Two partially overlapped graphene flakes were irradiated with a continuous wave CO2 laser, together with a current at a constant voltage of 30Â V. Raman spectrometer and transmission electron microscope (TEM) analyses showed the joining signal at a laser power density of 8Â W/cm2 with an irradiation time of 30Â s and a current of 25Â mA (30Â V) for 5Â min. The joining mechanism of graphene flakes was also investigated. We provide a novel route to realize large-area graphene joint for potential applications.
