제목 Synthesis of N-dopoed Graphene on SiC substrate by Pulsed Laser Annealing
초록 In the carbon material studies, chemically doped graphene has been studied to applicate high performance electronic device. Gas-phase doping on graphene by chemical vapor deposition (CVD) requires complicated transfer process which can cause unintentional doping and defects creation. In this work, we report a solid-phase synthesis of N-doped graphene on N-doped silicon carbide (SiC) substrate by pulsed laser (XeCl, 308nm) irradiation. Laser-induced synthesis provides a direct growth of nitrogen doped graphene on an insulating substrate without additional transfer procedure. The XPS analysis demonstrates that the C-N bonding conformation of the N-doped graphene was pyridinic-N type. Also, G band shift in Raman spectra shows that solid-phase doping can provide precise controllability of doping concentration by changing the dopant concentration of the SiC substrate
