The Fermi level of annealed low-temperature GaAs on Si-δ-doped GaAs grown by molecular beam epitaxy

The Fermi level of annealed low-temperature GaAs on Si-δ-doped GaAs grown by molecular beam epitaxy Photoreflectance has been used to study the Fermi level of annealed low-temperature GaAs in sample structures composed of low-temperature GaAs on top of Si-δ-doped GaAs. The diffusion of As precipitates across the interface between low-temperature GaAs and normal GaAs is observed by cross-sectional imaging via transmission electron [...]
