Fig. 2: Kondo characteristics of the Kn complexes.

a Measured dI/dV spectra of a bare Co adatom and a K1 adsorbed on different domains of the Au(111) surface. b Variation of TK of a K1 (or a bare Co adatom) versus its distance to another K1 (or bare Co adatom) on the Au(111) surface. c Measured dI/dV spectra of the Kn complexes (\(n=1,2,2^{\prime} ,3,4\)). The red lines are fits of the measured data to the Fano function (see Methods for details), and they have been shifted vertically for clarity. The measured data are acquired by placing the STM tip at positions marked by the black crosses in Fig. 1a, b under the background temperature T = 5 K. d TK of the Kn complexes extracted from experimentally measured and theoretically calculated dI/dV spectra. The red bars mark the standard deviations of experimental data. The dashed line is a linear fit of the measured TK of Kn (n = 1, 2, 3, 4). The circles (triangles) represent the values of TK determined by the heights (widths) of the calculated Kondo conductance peaks.
