Abstract

The nonlinear properties of piezoelectric quantum wells were studied to determine the intersubband transition time from the second (h₂) to the first confined heavy hole (h₁) state. Pump-probe experiments on CdTe quantum wells were performed using Ti:sapphire laser. For a pump resonant with e₁h₂ exciton, blueshift of e₁h₁ transition had risen during pump pulse as holes scattered from h₂ to h₁ and screened the piezoelectric field more efficiently. The possible contribution of exciton-exciton scattering, acoustic-phonon piezoelectric coupling, scattering from impurities and defects and phonon emissions were also discussed.
