Figure 7
(a) Large scale (365 × 850 nm2) STM topography image. (b) Cross-sections of the STM image along the blue and red lines, respectively, in (a). “CV” and “vdW” indicate CV and vdW regions of the surface. (c) dI/dV map corresponding surface area in (a). Ubias = + 0.2 V, Itun = 300 pA. Umod = 20 mV. We observe two distinct regions.
