Extended Data Fig. 2: Disappearance of the Kondo resonance.
From: Visualizing vibrational normal modes of a single molecule with atomically confined light

The Kondo resonance observed on the saddled CoTPP adsorbed on the Au(111) surface disappears on the flat CoTPP adsorbed on the Cu(100) surface. The gap distances are set at 1 nA, +0.2 V and 1 nA, −0.2 V for Au and Cu, respectively.
