Abstract:
We present high-resolution photoemission data from the Bi(111)-surface. The electronic structure of the semimetal close to the Fermi level has been found to change dramatically with respect to the well established bulk band structure. The Fermi surfaces observed for the electron and hole bands resemble those of the next group-V element, antimony, probably as a consequence of surface relaxation. This results in a relatively high surface charge density. The observed temperature dependence of the electron Fermi energy confirms this result.
