Abstract
Molecular dynamics was used to investigate surface relaxations of the three titanium dioxide phases (rutile, anatase and brookite). Atoms wi th small coordination relax much more than bulk like atoms. They under go vertical as well as lateral relaxations to compensate the missing b onds at the top layer. The driving force which determines the directio n of the relaxation seems to be the improvement of local environments of top layer atoms. (C) 1997 Elsevier Science B.V.
