33. A similar equation was derived by Beckmann et al. (Ref. 32) to describe the line shape of a Tamm state on vicinal Cu(100). There, however, the integration was carried out over the width distribution of single terraces, rather than the average terrace length in the region probed by the surface state.
34. Our value of (formula presented) is obtained by fitting a Lorentzian convolved with a Gaussian of 31 meV FWHM to the low-energy side of the spectrum. The total linewidth amounts to 68 meV. Very recent measurements at the highest resolution interpolate to a room-temperature linewidth of (formula presented): G. Nicolay and F. Reinert (private communication).

40. In a Kronig-Penney model the shift of the band bottom is given by (formula presented) where (formula presented) is the integral over the potential barrier. To adjust the energy of the band bottom we used a potential of the form (formula presented) with (formula presented) and (formula presented).
