TL;DR: In this paper, the authors investigated the influence of resonant states on hot electron transport in quantum wells and found that the matrix elements which determine scattering rates exhibit structure at the resonant energies, leading to suppression of scattering by polar optical phonons relative to non-polar optical and acoustic phonon scattering.
Abstract: In addition to bound states, quantum wells also produce resonant states in the continuum. While bound states have received considerable attention and are now the basis of device applications, the corresponding virtual states have hardly been studied. Here, we specifically investigate the influence of these resonant states on hot electron transport in quantum wells. We find that the matrix elements which determine scattering rates exhibit structure at the resonant energies. This leads to suppression of scattering by polar optical phonons relative to non-polar optical and acoustic phonon scattering. We discuss the effect that these states have on the capture and release of carriers by the quantum well.

Journal ArticleDOI
TL;DR: In this paper, the authors investigated the influence of resonance effects on the release of electrons by a quantum well and found that resonance effects led to a decrease in the rate of scattering by non-polar phonons from bound confined states to unbound continuum states.
