Improvement in peak intensities of PL from GaInAs and GaInAsN triple TQWs measured after different postannealing procedures at [(a) and (b)] and at [(c) and (d)].
Annealing-induced BS after annealing at and for GaInAs [panel (a)], and for GaInAsN [panel (b)] triple TQW structures. Curve (1): for the samples with a cap layer (set 1), curve (2): for the samples placed inside the GaAs box (set 2), curve (3): for the samples without caps (set 3), curve (4): for samples without caps (set 3), and curve (5): for the sample placed inside the GaAs box (set 2).
XRD(004) rocking curves for the GaInAs and GaInAsN QWs before and after annealing at [(a) and (c)] and at [(b) and (d)] for the samples with the caps (set 1) or for the samples placed inside GaAs box (set 2), or for those left uncapped (set 3). The spectra are vertically shifted for clarity.
