a The blue lines are the dI/dV spectra measured at different temperatures on the bright SD cluster of the Type-II 1T-TaS2 surface. The red lines are the thermally convolved Fano fits to the ZBP at each temperature. The purple cross in the inset shows the position for taking the temperature dependent dI/dV spectra. The spectra are vertically offset for clarity. b Evolution of the measured half width (Γ) at half maximum of the ZBP with temperature (blue squares with error bar). The error bars represent the uncertainty of the linewidths obtained from the thermally convolved Fano fits to the ZBP at each temperature. The solid red line is the best fit to the function \(\sqrt{{(\pi {k}_{B}T)}^{2}+{2({k}_{B}{T}_{K})}^{2}}\), which yields a Kondo temperature of TK ≈ 37 ± 6 K. c The blue lines are the dI/dV spectra measured with different external magnetic fields at 0.6 K. The red lines are the thermally convolved Fano fits to the ZBP at the measured magnetic fields. The spectra are vertically offset for clarity. Source data are provided as a Source Data file.
