Fig. 3: Correlation between the Fermi hole pocket and superconductivity.
a EDCs at (π/2, π/2) and hot-spot point for various dopings. Black dashed and green dotted lines guide the eye to the zero-energy intensity of each EDC. b EDCs at (π/2, π/2) with Gaussian function fitting results. Red, green, and blue solid lines correspond to AF peak, in-gap pristine peak, and background, respectively. The red vertical arrows in a, b denote Zhole obtained by the phenomenological method (Zhole_phn) and the Gaussian fitting (Zhole_fit). c, d, e Tc, Zhole_phn, Zhole_fit, and Δhole as a function of n, where Δhole is a binding energy of AF peak obtained by the Gaussian fitting. f Zhole_phn, Zhole_fit, and Δhole as a function of Tc. Error bars of Zhole_phn represent signal-to-noise error. Error bars of Zhole_fit and Δhole are determined based on the fitting error of the EDC peak.
