Abstract: The electric-field enhancement of the resonant Raman efficiency of confined optical phonon modes in a single quantum well has been observed in an asymmetrical n-type triple-barrier GaAs/AlAs resonant tunneling structure. The measurement takes advantage of an outgoing resonance with the e(2)-hh(1) exciton transition confined to the wide quantum well, and according to the polarization properties, the Frohlich interaction dominates the scattering mechanism. A fifteenfold increase is found from zero field to 7.5 x 10(4) V/cm, which results from break-down of the parity selection rules for the photon-exciton and the exciton-phonon coupling mechanisms.
