a Constant-current STM topography taken on the Type-II 1T-TaS2 surface (Vs = −500 mV, I = 20 pA). The yellow circles indicate the centers of the SD clusters. The dashed black lines show the region without the dark SD clusters. b dI/dV spectrum taken on the spot shown by the red arrow in a. c Constant-current STM topography taken on the Type-II surface with dark SD clusters (Vs = −150 mV, I = 30 pA). d dI/dV spectra taken on the bright and dark SD clusters shown by the purple and green arrows in c. The black arrow indicates the electronic state located slightly above the Fermi level in the dark SD cluster. e Spatially distributed dI/dV spectra along the red arrow in c. f Constant-current STM topography taken on the Type-II surface with dark SD clusters (Vs = −200 mV, I = 30 pA). g, h dI/dV maps taken on the same region as shown in f with 0 mV (g) and +40 mV (h) bias voltages, respectively. The green arrows in f–h indicate the positions of the dark SD clusters. The data shown in this figure are taken at T  =  4.3 K. Source data are provided as a Source Data file.
