<>   AB: A theoretical investigation of intersubband transitions in asymmetric
<>       coupled GaAs-AlxGa1-xAs quantum wells is presented in order to
<>       understand the role of interface phonons on intersubband scattering
<>       times estimated from photoluminescence up-conversion. Photoexcited
<>       carrier behavior is analyzed in relation to recent measurements and
<>       shows time constants for electron relaxation in agreement with
<>       experimental data. We show that interface modes are vital to
<>       intersubband relaxation in these structures. 

(1) (FK interface) IP-phonons independent of LO-phonons and TO-phonons
(2) IP-phonons supply extra reservoirs
(3) cf Ridley-1993 (etc) which implies IP+LO+TO becomes a hybrid-phonon
