- Abstract
It was shown that the electron energy spectrum in a disk-shaped potential well is characterized by two types of levels. One is characterized by a quantum number corresponding to carrier motion mainly along the disk axis. Energy intervals between such levels are large. As a rule, only a single electron level of this type can fit into the InAs quantum dot with GaAs surroundings. The second-type levels form a substructure with quantum numbers corresponding to carrier rotation about the polar axis and motion along the major disk axis. The distances between such levels are rather short. The theory makes it possible to determine the number of such levels as a function of the disk thickness and diameter and the conditions of the quantum dot transition into the quantum well with a large number of substructure levels.
