Extended Data Fig. 3: Kondo resonance states around three individual Cr dopants.
From: Symmetry-broken Kondo screening and zero-energy mode in a kagome superconductor
a-c, STM topographies of the three Cr dopants. d-f, dI/dV map for the Cr dopants shown in a to c. The yellow dots indicate the atomic locations of the Cr dopants. g-i, dI/dV spectra taken at the positions showing the strongest Kondo resonance. STM setup conditions: Vs = −500 mV, It = 100 pA (a); Vs = −80 mV, It = 40 pA (b); Vs = +80 mV, It = 20 pA (c); Vs = −5 mV, It = 300 pA, Vm = 0.05 mV, T = 0.4 K (g); Vs = −20 mV, It = 300 pA, Vm = 0.2 mV, T = 1.5 K (h); Vs = −20 mV, It = 300 pA, Vm = 0.2 mV, T = 1.5 K (i).
