Comparative Study of GaAs/GaInP and GaAs/AlGaAs Quantum Wells Grown by Metalorganic Vapor Phase Epitaxy

This is the authors' abstract. We don't add key points for this paper.

This paper presents results of a comparative experimental study aimed at producing GaAs/GaInP and GaAs/AlGaAs quantum wells (QWs) by metalorganic vapor phase epitaxy. The photoluminescence signal of the GaAs/GaInP QWs is shown to have a higher intensity (by a factor of 50–100) and, at the same time, a larger width (by a factor of ~2.5) in comparison with the GaAs/AlGaAs QWs. We analyze different approaches to controlling emission spectra of these QWs.
