Spatial extent of atomically well-ordered 1D interface state in single-layer 1T′-WSe2. a STM topograph of the 1T′–1H interface (Vs = − 525 mV, It = 0.2 nA). Dashed line shows interface location (see text). b Color-coded dI/dV spectra taken along the path marked by the arrow in a (f = 614 Hz, It = 0.6 nA, Vrms = 4 meV). c dI/dV curves extracted from b. d Experimental dI/dV map taken in the same region as a for Vs = − 130 meV. Dashed line shows same interface location as in a. e Average dI/dV linescan oriented along the X direction in d for Vs = −130 mV
