Fig. 2: Doping evolution of band topology and superconductivity.
From: A topological superconductor tuned by electronic correlations
a Evolution of the ARPES spectra as a function of the Te content (x) near the \(\bar{\Gamma }\) point using p-polarized 6 eV laser. b Same as (a) but using s-polarized 6 eV photons. c Resistance-vs-temperature curves for FTS thin films. The resistance values of each curve have been vertically offset for clarity. d Fitted spectral weight (S. W.) of the lower Dirac cone as a function of the Te content. e Fitted hybridization gap (\({\Delta }_{{Hyb}}\)) between the dxy and dyz bands as a function of the Te content. The error bars in panels (d) and (e) represent the statistical uncertainty derived from the fitting procedure. f Black circles are EDCs taken at -0.025 \({\mathring{\rm A} }^{-1}\). Red curves are fits to the EDCs (see Supplementary Note 7). Red and green shaded areas represent the components corresponding to the lower and upper Dirac cones, respectively. g Inverted second derivative curves corresponding to momentum-dependent EDCs in the range between −0.065 (top) and −0.165 \({\mathring{\rm A} }^{-1}\) (bottom). Dashed lines are guides to the eye indicating the band dispersion.
