Abstract
Recent measurements of electron escape from a nonequilibrium charged quantu m dot are interpreted within a two-dimensional (2D) separable model. Tnt: c onfining potential is derived from 3D self-consistent Poisson-Thomas-Fermi calculations. It is found that the sequence of decay lifetimes provides a s ensitive test of the confining potential and its dependence on electron occ upation.
