(double columns) STM spectroscopic features of lateral phase domains and DWs in MoTe2:Fe at 77 K. a STM topography showing a junction of three domains and DWs. Inset: atomic resolution image of MoTe2 showing Mo–Te–Mo chains. Scale bar: 5 nm. b Height profile across each of three DWs obtained from red, green and blue dots in a. Red and green represent the first-type protruded DWs and blue belongs to the second type. A ruler at the center shows the length of ten-unit cells for comparison. c Fourier filtered topography of the first type DW from the dashed rectangle in a. Red dashed lines mark ideal chain directions and the topography on the protruded area reveals the deviation of chain from the ideal straight line. d Differential conductance obtained from each DW in a. Red and green curves: the first-type protruded DWs; Blue curve: the second-type depressed DW; Black: the averaged curve obtained inside a domain, normalized at −100 mV, 100 pA. e, f Spatial mapping of differential conductance at −100 mV (e) and +100 mV (f), normalized at −50 mV, 100 pA
