Abstract

Abstract We report the successful fabrication of ZnSe p–n junction light emitting diodes in which Li and Cl are used as p-type and n-type dopants, respectively. These p-on-n structures emit blue light at room temperature. Double heterostructures in which the active region is either a ZnSe 0.9Te 0.1 layer or a ZnSe-ZnSe 0.9Te 0.1 multilayer have also been fabricated by molecular beam epitaxy. These structures emit green electroluminescence over a wide temperature range.
