Atomic layer epitaxy of II-VI quantum wells and superlattices

Atomic Layer Epitaxy (ALE) under ultra high vacuum conditions is a variation of MBE which makes use of a self-regulating growth process, leading to digital growth in steps of monolayers or even fractions of monolayers. We report on fundamental aspects of the ALE growth of tellurides and selenides, and give three examples on the physics of ALE-grown structures: (a) Phonon confinement in CdTe/ZnTe superlattices (b) Spin Sheet superlattices of cubic MnTe with CdTe and (c) Luminescence tuning in ultra-thin CdSe quantum wells embedded in ZnSe.
