Carrier density dependent localized carrier ratio under different parameters. Dark, red, and blue curves show comparison at different nc settings. Dark, orange, and violet curves show comparison at different k settings.
The schematic diagrams of LC5QW and L5QW.
Current dependent internal quantum efficiency (η-j) curves of LC5QW and L5QW. The samples are pulse excited at 1% duty cycle to avoid heat influence.
Fit results of LC5QW and L5QW. (a) Experimental data and fit results of LC5QW. (b) Experimental date and fit results of L5QW. Fit parameters are shown in red color in the figures.
CL results of samples at 6 K. Intensity (a) and wavelength (b) distributions of LC5QW. Intensity (c) and wavelength (d) distributions of L5QW.
CL spectra and wavelength histograms of samples LC5QW and L5QW. Histograms are fitted with a Gaussian function. Standard deviation σ is labeled in the figure.
Fit results of L8QW and L10QW. (a) Experimental data and fit results of L8QW. (b) Experimental data and fit results of L10QW. Fit parameters are shown in red color in the figures.
