Epitaxial growth and characterization of GaAs/Al/GaAs heterostructures
(Elsevier, 1990-04-01)
We report on transmission electron microscopy, secondary ion mass spectroscopy, X-ray and Raman scattering studies of GaAs/Al/GaAs heterostructures grown by migration enhanced epitaxy.
An STM study of molecular-beam epitaxy growth of GaAs
(Elsevier, 1993-01-10)
Scanning tunneling microscopy has been used to investigate molecular-beam epitaxy growth of GaAs. By quenching the sample during deposition, we have imaged the GaAs(001) surface as it appeared during growth. Large scale ...
The dynamical transition to step-flow growth during molecular-beam epitaxy of GaAs(00l)
(Elsevier, 1993-12-20)
Scanning tunneling microscopy studies have been performed on GaAs homoepitaxial films grown by molecular-beam epitaxy. Images show that in the earliest stages of deposition the morphology oscillates between one with ...
Charge-density domains in photoexcited quantum-well structures
(Elsevier, 1990-04-01)
We present theoretical and experimental results on the dielectric response of an electron-hole plasma confined to a quantum-well. Hartree calculations reveal large nonlinearities in the screening properties which, when ...
