Extended Data Fig. 4: Temperature-dependent Kondo resonance obtained near another Cr dopant.
From: Symmetry-broken Kondo screening and zero-energy mode in a kagome superconductor
a, dI/dV map showing the spatial distribution of the Kondo resonance. b-d, dI/dV spectra measured at different temperatures at the red dot shown in a. The solid curves represent the thermally convolved Fano (b), Frota (c) and Hurwitz fits (d). e, Temperature dependence of the HWHM extracted from the fits in b to d. The solid lines in b-d represent the fits to the empirical expression of \({HWHM}=1/2\sqrt{{(\alpha {k}_{B}{T}_{{eff}})}^{2}+{(2{k}_{B}{T}_{K})}^{2}}\).
