In this work, we have studied the inter-and intra-subband scattering of hot electrons in quantum wells using the hot electronneutral acceptor luminescence technique. We have observed direct evidence of the emission of confined optical phonons by hot electrons excited slightly above the n ¼ 2 subband
The correlation between the electron spin relaxation time t s and the hetero-interface roughness in (11 0)-oriented GaAs/AlGaAs multiple-quantum wells (MQWs) was investigated using growth interruption during molecular beam epitaxy growth. t s was characterized using polarization-and time-resolved PL
