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.Comment: 8 pages, 2 figures, conference paper to appear in Physica Status
Solidi (a), we give a support of our recent predictions for diamond(111),
