  text: We have investigated the stacking of self-assembled cubic GaN quantum dots
    (QDs) grown in Stranski–Krastanov (SK) growth mode. The number of stacked layers
    is varied to compare their optical properties. The growth is in situ controlled
    by reflection high energy electron diffraction to prove the SK QD growth. Atomic
    force and transmission electron microscopy show the existence of wetting layer
    and QDs with a diameter of about 10 nm and a height of about 2 nm. The QDs have
    a truncated pyramidal form and are vertically aligned in growth direction. Photoluminescence
    measurements show an increase of the intensity with increasing number of stacked
    QD layers. Furthermore, a systematic blue-shift of 120 meV is observed with increasing
    number of stacked QD layers. This blueshift derives from a decrease in the QD
    height, because the QD height has also been the main confining dimension in our
    QDs.
