Reflection high-energy electron diffraction oscillations during epitaxial growth of artificially layered films of (BaCuOx)m/(CaCuO2)n

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 oscillation...

Sumario: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. © 2001 Elsevier Science B.V.
