On the hybridization of zero-dimensional Frenkel and Wannier-Mott excitons

4 On the hybridization of zero-dimensional Frenkel and Wannier Mott excitons 

In the previous sections we have considered the hybridization of Frenkel and Wannier-Mott excitons in two-dimensional (quantum wells) and one-dimensional (quantum wires) geometries. For the sake of completeness, in this subsection we shall briefly and qualitatively discuss the zero-dimensional (0D) case that corresponds to a quantum dot geometry. We have in mind a configuration where a semiconductor QD is located near a small size organic cluster or is just covered by a thin shell of an organic material. 

There are the following qualitative differences in the hybridization scenario in this geometry as compared to those in the 2D and ID cases. The presence of a translational geometry along planes or wires has resulted in a selection rule 

Interesting results of the studies of the strong coupling regime of Wannier-Mott excitons in a quantum dot lattice embedded in organic medium and in dendrites and also unusual nonlinear properties of such structures can be found in the articles by Birman and coworkers (33)-(37).
