Extended Data Fig. 5: Bias-dependent dI/dV maps of (4,2)-JGNR across a wide energy window.
From: Janus graphene nanoribbons with localized states on a single zigzag edge
a, d, Constant-current dI/dV maps of (4,2)-JGNR recorded at various sample biases marked in b by the dashed vertical lines (Vac = 10 mV). b, dI/dV point spectrum of (4,2)-JGNR on Au(111) acquired at the positions marked in panel c (yellow and green cross). Grey dashed line spectrum represents the Au(111) reference spectrum (Vac = 20 mV). c, Constant current STM images of (4,2)-JGNR, (Vs = 800 mV, It = 200 pA, CO-functionalized tip).
