| 英文摘要 | When injected electrons in a quantum well first experience an intersubband relaxation process before their escaping by tunneling through a double-barrier structure behind, the magnetic suppression of intersubband lo or la phonon scattering can give rise to a noticeable nonthermal occupation in higher-lying subbands. that is clearly verified by the relative intensity ratio of the interband photoluminescence spectra for e-2-hh1 and e-1-hh1 transitions. the observed phenomenon may provide an effective method for controlling intersubband scattering rate, a central issue in so-called quantum cascade lasers, and facilitating the population inversion between subbands in quantum wells. |
