Abstract
We employ the configuration interaction (CI) method in order to discuss many-particle properties of quantum dots as functions of the dots’ size, shape and composition. Single-particle states, necessary for the CI-basis expansion, are calculated by eight-band k⋅p theory. Special emphasis is put on the role of strain and piezoelectricity, where the latter is treated up to second order. Finally, we address the inverse problem of fitting spectroscopic data to our detailed theoretical model leading to the determination of size, shape and composition as adjustable parameters.
