GaInAs/GaAs strained-layer superlattices grown by low pressure metalorganic vapor phase epitaxy

Abstract
Strained‐layer superlattices (SLS’s) of GaxIn1−xAs/GaAs (x≂0.8–0.9) have been grown by low pressure metalorganic vapor phase epitaxy. The reactants were trimethylgallium, trimethylindium, and arsine. The structures were characterized by Auger profiling and low‐temperature photoluminescence. These measurements show that high quality SLS’s with interface widths no larger than 25 Å and very narrow luminescence peaks (6.5 meV) similar to the best structures grown by molecular beam epitaxy, can be easily grown by low pressure metalorganic vapor phase epitaxy.
