Growth and properties of In-doped CdMnTe-CdTe superlattices

Abstract
The first successful substitutional doping of dilute magnetic semiconductor superlattices composed of alternating layers of CdMnTe and CdTe is reported. These n-type In-doped multilayer structures were prepared using a new thin-film growth technique, photoassisted molecular beam epitaxy, in which the substrate is illuminated with visible light during the deposition process. The electrical, optical, and structural properties of the CdMnTe-CdTe superlattices are discussed.
