Demonstrating Kondo behavior by temperature-dependent scanning tunneling spectroscopy
Researchers used a Hurwitz-Fano lineshape model to analyze spectroscopic indicators of Kondo behavior in a spin-1/2 system measured by scanning tunneling spectroscopy. This novel approach successfully extracted accurate intrinsic Kondo linewidths, providing experimental proof for an analytic expression describing the temperature dependence of the resonance, validating theoretical predictions.
