Abstract

Depressurization of Si from its metallic β-Sn modification results in a dense metastable form (Si-III), which is semimetallic and persists indefinitely at ambient pressure. We have investigated possible reconstructions of the Si-III (001) surface using ab initio pseudopotential calculations and find that a configuration comprised of adatoms and symmetric dimers has, to the best of our knowledge, a lower surface enrgy than any other previously reported surface of silicon. © 1994 The American Physical Society.
