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 ΒΌ 2 subband
Experimental results on high electric field longitudinal transport in GaAs/AlAs and \(G a A s / G a_{1-x} A l_{x} A s\) multiple quantum wells (MQW) are presented and compared with the prediction of a dielectric continuum model. We draw from our experiments the following four conclusions. (i) In \(
