Abstract

We study processes in which excited electrons in semiconductor quantum wells lose energy by emitting slab LO phonons of the quantum well, namely, bulklike confined phonons and interface phonons. We consider both intrasubband and intersubband relaxation and show that, consistent with a recent experimental finding, phonon selection rules are responsible for a large reduction of intersubband relaxation rates.
