The electron capture time via an electron-polar optical phonon interaction is calculated considering the confinement of a phonon in a GaAs quantum well laser structure. The effect of the phonon confinement decreases the electron capture time about twice comparing the electron capture time obtained from the interaction of an electron with the bulk phonon. |
