    • The spectra are similar to those in the experiment described in (20), where large mesas are delineated, corresponding to the excitation of ~4000 dots.

    • note
    • Simultaneous emission from two eigenstates 30 meV apart would either give a bimodal distribution or add a "shoulder" to the Gaussian peak, making it asymmetric.

    • The best estimates of the CL spatial resolution in these experiments were done taking the narrower FWHM of intensity-variation peaks in line scans obtained for a fixed wavelength.
