Ai. Filin et al., INTERSUBBAND RELAXATION OF 2-DIMENSIONAL ELECTRONS IN A PARALLEL MAGNETIC-FIELD, Semiconductor science and technology, 13(7), 1998, pp. 705-708
The intersubband relaxation rate of a two-dimensional electron gas as
a function of a parallel magnetic field has been derived from time-res
olved optical spectra. A theoretical model of the intersubband scatter
ing due to roughness of the interface has been developed. A good agree
ment between experimental data and model calculations has been achieve
