Abstract

Technological advances have produced both the ability and the need to confine electrons in semiconductors to regions which are effectively two- and one-dimensional, and even into "boxes" so small that they are called "quantum dots".

This talk will describe some of the technological advances which make this possible, some of the interesting physics that one can study in these systems (including electronic transport properties, as well as optical response), and even some of the suggested applications.
