Abstract

Pulsed laser deposition in molecular-beam epitaxy environment has been used to grow high quality BaCuOx/CaCuO2 superlattices. In situ reflection high energy electron diffraction (RHEED) shows that the growth mechanism is two-dimensional. Furthermore, weak but reproducible RHEED intensity oscillations have been monitored during the growth. Ex situ X-ray diffraction spectra confirmed the growth rate deduced from RHEED oscillations. Such results demonstrate that RHEED oscillations can be used, even for (BaCuOx)(2)/(CaCuO2)(2) superlattices. for phase locking of the growth. (C) 2001 Elsevier Science B.V. All rights reserved.
