The amplitude and periodicity of the reflection high-energy electron diffra
ction (RHEED) oscillations displayed strong temperature dependence in homoe
pitaxy of SrTiO3(STO) films. Combining with the AFM observations, the resul
ts suggest that the oscillations are not directly related to the layer-by-l
ayer growth. (C) 2000 Elsevier Science B.V. All rights reserved.
