Slowly decaying quasistationary electron states in spherical heavy quantum dots
The energy spectrum of an electron in a spherical potential-hump heteroinclusion with a large effective mass is shown to be characterized by a set of quasidiscrete levels with large values of the angular momentum /. The lifetimes of quasistationary states in the hump increase with increasing I, i.e., with increasing excitation of the state. Energies and lifetimes of the quasistationary states are calculated numerically on the basis of selected parameter values. © 1994 American Institute of Physics.
