The e ects of desorption and di usion of indium adatoms on the photoluminescence (PL) from InAs self-assembled quantum dots (QDs) are investigated by introducing growth interruptions after QD formation. Large, low-density and small, high-density QDs were grown by molecular beam epitaxy using low (0:

We have characterized self-assembled InAs quantum dots grown on the top of a single InGaAs/GaAs quantum well (QD's:QW) by measuring photoluminescence (PL) spectra as an effective technique. We have found that the linewidths of the PL peaks for the QD's:QW are narrower than that for the InAs quantum
