Extended Data Fig. 4: Correlation between G- and G′-band frequencies and FWHMs.
From: Localization of lattice dynamics in low-angle twisted bilayer graphene

a, b, The frequencies (a) and FWHMs (b) are shown for the data displayed in Fig. 4. The twist angle for each point is labelled. The red curved arrow in b indicates a maximum in FWHM observed near the magic angle.
