a STM image of the 1T′-MoTe2 surface. b Three symmetry-equivalent directions (black arrows) of structural distortion in the 1T structure and their three opposite directions (green dotted arrows). c Averaged dI/dV spectra obtained at left area (black line) and right area (blue line) and dI/dV spectrum obtained at the position indicated by the red dot in (d) (red line). d-e STM images of 60° glide-reflection and 120° two-fold rotation boundaries, respectively. f Averaged dI/dV spectrum obtained at left area (black line) and dI/dV spectrum obtained at the position indicated by the green dot in (e) (green line).
