“…In recent years, intense studies have been carried out on excitonic properties of ZnCdSe/Zn͑S͒Se QW's in terms of their usefulness for blue-green laser diodes. 3,4 Since the well layer in the structures is under compressive strain, the lowest excitonic transiton occurs between the nϭ1 conduction electron and nϭ1 heavy hole, generally designated as E x1hh . The solid composition of Cd in Zn x Cd 1Ϫx Se well layers is typically about 15-20% in the device structures.…”
