Room temperature PR spectra of four MQW samples.
Room temperature SPS—dashed lines, and DSPS—solid lines, spectra of all investigated MQW samples.
The comparison of room temperature DSPS, PR, and PzR spectra for MQW sample: solid lines. With dashed lines the result of fitting to experimental data is shown. Arrows indicate the transition energies obtained from fitting to the experimental data.
The QW transitions energy dependence on Sb content. Solid and dashed lines are taken from theoretical calculations. Squares, triangles, and circles represent the energies obtained from fit to PR data, while stars represent DSPS data. Vertical line shows the Sb content for which QW alignment changes from type-I to type-II.
