Abstract

Femtosecond study of the hole relaxation after resonant intersubband excitation in a quasi-two-dimensional semiconductor was carried out. Midinfrared pump-probe studies on p-types Si_0.5Ge_0.5/Si multiple quantum wells revealed an intersubband relaxation time of 250 fs from the second heavy-hole back to the first heavy-hole subband.
