From: Graphene wrinkling induced by monodisperse nanoparticles: facile control and quantification
Correlation of the parameters representing the spatial distribution of nanoparticles and level of wrinkling of the 1-LG layer.
The left panel shows the mean nanoparticle density, NNPs (black points) and mean interparticle distance, dNP-NP (red points) in context of the relative delaminated area, Aw determined by the analysis of the AFM data. The data roughly scales with NNPs and 1/dNP-NP for increasing relative intensity of the G2. The right panel correlates the Aw (obtained from AFM) to the ratio of the integral intensity of the G2 (attributed to the delaminated fraction of the 1-LG) and G1 modes (black points), which results in a robust linear dependence. Analogues plot is shown for the pair of G’1 and G’2 modes (red points), which follows the same trend with much lower slope. The grey outlying point corresponds to the sample with the largest Aw values (GNP3), which G’ is better analyzed by using a single peak with larger FWHM.
