    • In such large mesas typically single dot emission cannot be observed since so many QDs are involved that their spectral lines overlap, resulting in a broad emission band. For one of the studied large mesas we were, however, able to isolate a few sharp emission lines which allowed for determining the ZPL width.

    • This small variation might also arise from optical inactivity of QDs that are located very close to the surfaces, because carriers become trapped at the sidewalls before they are captured by the QDs.

    • Off-diagonal exciton contributions, such as those suggested in T. Takagahara, Phys. Rev. B 60, 2638 (1999) for large "interface QDs," give negligible contributions to the exciton linewidth in the present systems.

    • Anharmonic exciton-phonon couplings were suggested by Ref. 25, but it was later shown that they do not give exciton line-widths if the phonons have zero widths.
