Band gap engineering in II–VI based heterostructures

Cd x Hg 1− x Te/CdTe quantum wells and superlattices have been designed for light emission in the 1–4 μm range. These structures have been grown by molecular beam epitaxy. Under laser excitation, they show efficient light emission (up to 300 K in the case of superlattices). Room temperature laser em...

Zusammenfassung:Cd x Hg 1− x Te/CdTe quantum wells and superlattices have been designed for light emission in the 1–4 μm range. These structures have been grown by molecular beam epitaxy. Under laser excitation, they show efficient light emission (up to 300 K in the case of superlattices). Room temperature laser emission has been observed from a separate confinement heterostructure.
