Spontaneous formation of nanostructures during epitaxial growth is one of the most successful techniques for in situ fabrication of quantum dots (QDs). We describe new size and shape engineering procedures for the growth of layers of stacked QDs, resulting in a significant narrowing of the size and shape distribution. Transmission electron microscopy (TEM) and photoluminescence (PL) indicate that the main effects of this size and shape engineering are to convert the quantum dots into a population of quantum disks with highly uniform height and diameter.
