ARPES spectra (left panels) and corresponding second-derivative of the intensity (right panels) for the stated Rb coverages. The colored overlays are a guide to the eye inferred from the second-derivative features, highlighting hybridized surface bands (red dashed curves), trivial surface states (blue dashed curves) as well as the BVB and BCB (orange dashed curves). The dashed lines in (a) mark the coverages in (b)-(d). The spectra were extracted along the dashed red line shown in the inset with the Fermi surface in (b). The photon energy applied for the measurements is 18 eV.
