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...
