Extended Data Fig. 1: Height dependence of the tunnelling current.
From: Real-space imaging of the band topology of transition metal dichalcogenides
(a) Image to the left shows a flattened current image acquired at -1.9 V near the Γ point, with the raw current shown in grayscale. As the tip is lowered toward the sample (blue profile), the charge density position shifts as the tunnelling becomes dominated by states at K. (b) At -1.4 V, where only K states contribute, the charge density remains unchanged with tip height. Scale bars are 0.5 nm.
