a STM image of 1T’–MoTe2 with NonSymC2 and SymC2 GB (Vs = –240 mV, I = 0.1 nA). b dI/dV maps obtained in the NonSymC2 GB for bias voltages Vs = 20 mV and 58 mV. c dI/dV Spectra acquired along the NonSymC2 GB from 1 to 12 marked in the right in (b). d LDOS line profiles of the NonSymC2 GB at the energies of N = 1 and N = 2, acquired along the dotted black and red lines in (b).
