Abstract:

A number of problems involving the electronic properties of artificially structured semiconductors have been studied. The study of the ground state and the elementary excitations of a double quantum well system has revealed the existence of a novel excitonic charge density wave state. Donor states, both singly and doubly occupied, in a modulation doped quantum well have been investigated. Magnetic polaron effects in a variety of artificial structures have been studied.
