摘要：

The effect of the electron-phonon interaction on the second-order susceptibilities are investigated theoretically for electrons confined in half parabolic quantum wells. We found that the electron-phonon interaction in GaAs based wells increases the second-order susceptibilities with up to a factor of 10-40. (c) 2006 Elsevier B.V. All rights reserved.
