Abstract

A fundamental issue in quantum mechanics concerns the manner in which the discrete level spectrum of an isolated system is modified when it is coupled to some external, macroscopic measuring environment. From an experimental perspective, an ideal system for the study of this issue is provided by semiconductor quantum dots, which are quasi-zero dimensional semiconductor structures in which the flow of electrical current is confined on length scales comparable to the size of the electron itself [1]. The key components of a quantum dot are illustrated schematically in Fig. 6.1(a), in which the basic idea is that current flow between the macroscopic source and drain reservoirs is forced to occur via a central cavity.
