From: Towards large-scale in free-standing graphene and N-graphene sheets
(a) Graphene sheets freely suspended on a glass substrate; (b) the same sheets spread over the glass with a metallic scalpel; (c) Raman spectra of the samples; (d) NEXAFS spectra of the graphene sheets spread over silicon substrate. Normalized to σ* resonance peak at \( \sim \)291.7 eV, indicated to observe angle dependence.
