Abstract
In previous chapters we have discussed the electronic properties of ideal heterostructures within a single-particle approach. However, realistic structures have impurities and geometrical imperfections that affect electronic states. Even more importantly, the electrons interact with each other and with other elementary excitations. In this chapter we describe the formation of localized electronic states due to interaction with structure imperfection and impurities, as well as excitonic states. As in the bulk case, such localized states play an important role in the optical and transport properties of semiconductor heterostructures.
