BERYLLIUM CHALCOGENIDE ALLOYS FOR VISIBLE LIGHT EMITTING AND LASER DIODES

Abstract. We give a brief overview of the current advances in the development of green light emitting and laser diodes (LEDs and LDs). We review problem of rapid degradation of LDs based on II-VI material family. We cover recent advances in this area stressing the development of novel beryllium chalcogenide alloys. We discuss an increase in the lifetime of beryllium-containing light emitters recently reported by several research groups. These results demon-strate that beryllium chalcogenide alloys are attractive for the design of visible light emitters. 1
