Extended Data Fig. 11: Temperature dependence of Kondo resonance height and width in MATTG.
From: Resolving intervalley gaps and many-body resonances in moiré superconductors
a, dI/dV spectra focusing on the Kondo resonance on MATTG device #2 for filling factor ν = 1.2 at several temperatures. Black arrows indicate the positions of the resonance peaks. b, Full width at half maximum of the resonance extracted from a, obtained by Lorentzian fits after subtracting a smooth background. Dashed red line is a formula derived from previous literature62 assuming single Kondo impurity. c, dI/dV spectra focusing on the Kondo resonance on MATTG device #3 for filling factor ν = −1.63 at several temperatures. d, Full width at half maximum of the resonance extracted from c, obtained by Lorentzian fits after subtracting a smooth background. Dashed red line is a formula derived from previous literature62 assuming single Kondo impurity.
