Molecular dynamics simulations of a set of possible configurations of the (
0001) oxygen-terminating surface were carried out in the microcanonical ens
emble in a Cr2O3 slab composed of 960 particles. Our simulations suggest th
at the oxygen-terminating layer has the same probability of occurring as th
e chromium-terminating surface in the real system due to the presence of su
perficial lattice defects. (C) 1999 Elsevier Science B.V. All rights reserv
