摘要
Monocrystalline GaAs/ErAs/GaAs structures are fabricated by migration-enhanced epitaxy at 320-degrees-C. When the ErAs layer thickness is less than 3 monolayers, reflection high-energy electron diffraction patterns, double crystal x-ray diffraction analysis, and transmission electron microscopy observations show successful overgrowth of GaAs on the ErAs layer. Distinct satellite peaks are observed in an x-ray rocking curve of an ErAs/GaAs superlattice grown under a similar condition, indicating that high-quality multilayer structures with very thin ErAs layers can be fabricated by migration-enhanced epitaxy.
