Figure 2
Stacked Raman spectra along the wrinkle, which are offset for clarity. The position of the spectra is indicated in panels (b,e,h,k) with black+. On the right side, Raman spectral maps of the fitted intensity, Raman shift and FWHM are shown for the D-like (b–d), G (e–g), RTO (h–j) and RLO (k–m) modes. The black scale bar in each map corresponds to 500 nm.
