Schematic of band edge alignment and PL/PR transitions in QWs. For , no confinement is for topmost lh valence subband. For the confinement is type I and for it is type II.
(a) PR spectra for single QWs at room temperature. GaNAs-related features are zoomed in, their fitting energies are marked by arrows and digits. (b) vs extreme index for GaAs-related features, the data with fit to a straight line for the 4.7% and 5.9% samples, respectively.
(a) Conduction-band (CB) and topmost valence-band (VB) for . (b) Zoomed-in topmost lh subband. Horizontal dashes indicate GaAs CB and VB. Solid lines by BAC model, dash-dot dots and dash dots by nonlinearly N-dependent and , respectively
Transition energies by fitting the PR spectra and by model-solid simulation for three single QWs.
