Extended Data Fig. 7: Spectral simulations compared with experimental ARPES data.
From: Pseudogap in a crystalline insulator doped by disordered metals
The experimental band structure is taken from black phosphorus whose surface is doped by different kinds of alkali metal (Na, K, Rb and Cs), as marked at the bottom right of each panel. This series of ARPES spectra was taken along ky (left column), ks (middle column) and kx (right column). Each dataset is directly compared with corresponding spectral simulations at p-wave resonance for Na and d-wave resonance for K, Rb and Cs (Methods). The bottom energy of spectral simulations is limited by that of the non-interacting (bare) band, which is the reason that those for Rb and Cs are slightly cut at a binding energy of 0.42–0.45 eV.
