From: Towards large-scale in free-standing graphene and N-graphene sheets
(a) SEM image of N-graphene sheets (QAr = 1200 sccm; QEt = 55 sccm, QN2 = 5 sccm). (b) Raman spectra obtained at different partial N2 flows (P = 2 kW, QAr = 1200 sccm, QEt = 15 sccm); (c,d) Detailed C 1s and N 1s regions with corresponding fittings (P = 2 kW, QAr = 1200 sccm, QEt = 15 sccm, QN2 = 5 sccm).
