Growth and characterization of low threshold-current-density II-VI blue-green laser diodes grown by molecular beam epitaxy

We describe the growth and characterization of Zn/sub 1-x/Mg/sub x/S/sub y/Se/sub 1-y//Zn/sub 1-u/Cd/sub u/Se-based laser diodes using ZnSeTe graded-gap contacts, and related materials. Contact performance, degradation and defect generation, thermal transport, and life testing are discussed.
