摘要：

The authors present a photoluminescence study of the optical and structural properties of ZnSe/CdSe/ZnSe layers grown by atomic layer epitaxy, embedded within barriers of ZnCdMgSe lattice-matched to the InP (001) substrate. The authors show that a few ZnSe monolayers surrounding the CdSe layer inhibit quantum dot formation and induce the growth of quantum islands of CdSe. For the case of a 2 monolayers coverage of CdSe, quantum islands of 1 and 2 monolayers thickness were observed. These quantum islands (or quantum terraces) present intense luminescence even at room temperature. (C) 2016 American Vacuum Society.
