Abstract
We have performed photoemission studies on high-quality samples with various δ. Our results show a clear chemical-potential shift (0.15–0.2 eV) as a function of doping. This result and the existing angle-resolved-photoemission data give a rather standard doping behavior of this compound in its highly doped regime.
