Extended Data Fig. 4: Spatial localization of edge state of 5-ZGNR and TDZ edge state of (5,2)-JGNR.
From: Janus graphene nanoribbons with localized states on a single zigzag edge
a, Constant current STM images of 5-ZGNR, (Vs = −800 mV, It = 200 pA, CO-functionalized tip). b, Colour-coded dI/dV spectra collected as a function of position along the red dotted line (from left to right) in a (Vac = 20 mV, Vs = 1.5 V). The dashed line overlayed on b is the point dI/dV spectrum acquired at the position labelled with a cross in a. c, Constant current STM images of (5,2)-JGNR, (Vs = −800 mV, It = 200 pA, CO-functionalized tip). d, Colour-coded dI/dV spectra collected as a function of position along the red dotted line (from top to bottom) in c (Vac = 20 mV, Vs = 1.5 V). The dashed line overlayed on d is the point dI/dV spectrum acquired at the position labelled with a cross in c.
