Abstract

Due to the promising utilizations in nanoelectronics, doping-tunable graphene is paid extensive attentions. Nevertheless, a harmless approach to dope/co-dope graphene in a controllable and easy way with low cost is still unattainable. Herein, through seeding of 0D N & S dual-doped graphene quantum dots (N & S dual-doped GQDs) on a catalytic substrate and then dynamic chemical vapor deposition (CVD), a monolayered dual-doped graphene film is demonstrated. The concentrations of dopants in graphene are strictly discerned in accordance with preliminary seeding for dual-doped GQDs. Through the monitoring of growing process, the research elucidates the growth mechanism of the graphene, and unveils..
