(a) The band dispersion near Fermi momentum ( k _F) for single-layer FeSe/STO in the superconducting state. The spectra are symmetrized with respect to the Fermi energy. (b) Temperature dependent behavior of symmetrized spectra. (c) Temperature dependent gap-size and BCS fitting. Panels (b) and (c) are reprinted with permission from Ref.
