Abstract
Ultrafast hole dynamics in Si0.5Ge0.5/Si multiple quantum wells is studied with resonant excitation of the HH1 → HH2 heavy-hole intersubband transition. Pump-probe experiments with 150-fs mid-infrared pulses demonstrate intersubband scattering and thermalization on a subpicosecond timescale.
