Abstract

There are a variety of situations in which carriers sit in small 3-D quantum boxes containing a small number of electrons per box. These dots are characterized by periodic, oscillatory fluctuations in their magnetoconductance, which replicate the partial density of states in the dot itself. Hence, the measured magnetoconductancc is a reflection of the energy spectrum of the dot. This carries over to arrays of dots, with the exception that new "superlattice" behavior can be observed in these structures. In this paper, we discuss recent quantum mechanical calculations of the properties of single dots and arrays of dots, and compare the results with experimental observations.
