(a) Large-scale constant current STM topography image (50 nm × 50 nm; Vs = −0.2 V; It = 0.02 nA) and (b) zoom in (10 nm × 10 nm) for an easier appreciation of details of (3,1)-chGNRs on Au(322). (c) Second derivative of the photoemission intensity reflecting the valence band dispersion (raw photoemission intensity data are displayed in the Supporting Information). Dotted lines mark the center of first, second, and third Brillouin zones.
