Tunneling escape rates of electrons from quantum dots with two quasibound states

Based upon the tunneling Hamiltonian, the lifetime of electrons in the quasibound state of quantum dots with single and two quasibound states is calculated analytically. It has been shown exactly that the lifetime of electrons remaining in one of the quasibound states for two-quasibound-state quantum dots is shorter than that for single-quasibound-state quantum dots with the same resonant energy. © 1995.link_to_subscribed_fulltex
