Abstract
Two inequivalent threefold symmetric adatom models for the Si(111) ✓3x✓3- Al reconstruction are examined with self-consistent pseudopotential density functional total energy and force calculations. These calculations indicate that the Al is positioned in the site above the second layer, rather than in the hollow site. The calculated dispersion of the occupied surface states is in agreement with angle resolved photoemission experiments.
