Query: Reconstructions of diamond (100) and (111) surfaces: Accuracy of the
  Brenner potential   We present a detailed comparison of the structural predictions of the
effective many-body Brenner potential with those of ab-initio studies for known
reconstructions of diamond (100) and (111) surfaces. These results suggest high
reliability of the Brenner potential for dealing with carbon-based structures
where different types of bonding are present at the same time.
