Abstract
Ge(211) and Si(211) surfaces are being investigated by ab initio methods. E xtensive relaxations are found to take place and the atomic geometries are altered as far down as 8 Angstrom. The dangling bonds of the edge atom make s both surfaces metallic, and several other surfaces states are found. Some smaller definitive differences between the Ge(211) and the Si(211) in geom etry and electronic structure are also investigated. (C) 1999 Elsevier Scie nce B.V. All rights reserved.
