Growth of ZnSe/MgS strained-layer superlattices (SLSs) has been carrie
d out by molecular beam epitaxy. The crystal quality of SLSs degraded
with MgS thickness of more than about 3 monolayers. Photoluminescence
due to the transition between quantized levels was observed. Photolumi
nescence peak energies higher than 3.0 eV at 77 K were observed, which
are comparable to that of ZnMgSSe quaternary material. (C) 1995 Ameri
