Extended Data Fig. 10: Raman mappings and scattering plots of the nanoporous graphene film.
From: Cascaded compression of size distribution of nanopores in monolayer graphene

a, Processing stages of the samples with different shrinkage time. The fitted shrinkage rate is 0.078 s−1. b–d, The Raman mapping and scattering plot of the sample after ten cycles of cascaded compression. e–g, The Raman mapping and scattering plot of the sample with extra 30 s shrinkage. The samples are transferred onto SiO2/Si substrate.
