Abstract We report on a simple theoretical model allowing to investigate the rapid thermal
annealing induced quantum dots intermixing and consequent inhomogeneous broadening.
In this model, where the 3D Schrödinger equation has been solved, by the orthonormal
wave function expansion method, for strained InAs QD, we assume a lens-shaped QD with a
uniform indium composition and a constant aspect ratio during the intermixing process. The
size and aspect ratio for as-grown InAs QD, have been estimated by matching the …
