Jacak L., Hawrylak P., Wojs A. Quantum Dots

Springer, 1998. — 176 p.The electronic structure of quantum dots, including the energy quantization of the single-particle states (due to spatial confinement) and the
evolution of these (Fock-Darwin) states in an increasing external magnetic field, is described. The properties of many-electron systems confined in a dot are also studied. This includes the separation of the center-of-mass motion for the parabolic confining potential (and hence the insensitivity of the transitions under far infrared radiation to the Coulomb interactions and the number of particles - the generalized Kohn theorem) and the effects due to Coulomb interactions (formation of the incompressible magic states at high magnetic fields and their relation to composite jermions), and finally the spin-orbit interactions. In addition, the excitonic properties of quantum dots are discussed, including the energy levels and the spectral function of a single exciton, the relaxation of confined carriers, the metastable states and their effect on the photoluminescence spectrum, the interaction of an exciton with carriers, and exciton condensation.
The theoretical part of this work, which is based largely on original results obtained by the authors, has been supplemented with descriptions of
various methods of creating quantum-dot structures. It includes an extensive overview of the experimental studies of quantum dots, such as work on far infrared, photoluminescence and capacitance spectroscopies.
