Abstract


A calculation is reported for the probability of electron capture by a single quantum well that takes into account the quasi-two-dimensional electron system in the quantum well. The influence of continuum resonances, which are localized in the vicinity of the quantum well at energies above the barrier, were considered in the calculations. The scattering rate by optical-phonon deformation potentials as function of the incident electron energy and the well width are discussed.

Keywords
