Query: Influence of quantum dot geometry on p-shell transitions in differently
  charged quantum dots   Absorption spectra of neutral, negatively and positively charged
semiconductor quantum dots are studied theoretically. We provide an overview of
the main energetic structure around the p-shell transitions, including the
influence of nearby nominally dark states. Based on the envelope function
approximation, we treat the four-band Luttinger theory as well as the direct
and short range exchange Coulomb interactions within a configuration
interaction approach. The quantum dot confinement is approximated by an
anisotropic harmonic potential. We present a detailed investigation of state
mixing and correlations mediated by the individual interactions. Differences
and similarities between the differently charged quantum dots are highlighted.
Especially large differences between negatively and positively charged quantum
dots become evident. We present a visualisation of energetic shifts and state
mixtures due to changes in size, in-plane asymmetry and aspect ratio. Thereby
we provide a better understanding of the experimentally hard to access question
of quantum dot geometry effects in general. Our findings show a new method to
determine the in-plane asymmetry from photoluminescense excitation spectra.
Furthermore, we supply basic knowledge for tailoring the strength of certain
state mixtures or the energetic order of particular excited states via changes
in the shape of the quantum dot, which is highly interesting e.g. to understand
relaxation paths.
