Abstract

Strong electrostatic field effects on the resonance states of the quantum-confined electron, heavy hole, and light hole in a quantum well are investigated by a continuous-spectrum approach based on Weyl-Titchmarsh theory. The field-ionization mechanism by numerically calculated tunneling and radiative recombination lifetimes of various excitons in several resonance energy states is discussed. The crossover of the tunneling lifetime between the ground-state electron and the first-excited-state heavy hole occurs for fields of more than 100 kV/cm.
