Abstract

The rate of carrier relaxation from unconfined barrier states to the confined states of a quantum well (QW) has important consequences for opto-electronic devices, and is of fundamental interest, since it probes the coupling between 2D and 3D carriers. Previous calculations of the so-called capture time have primarily been based on the electron-LO-phonon (e-LO) interaction,^1,2 whereas little attention has been paid to the contribution from carrier-carrier (cc) scattering.^3,4
