Abstract

We have studied the relaxation dynamics of photoexcited electrons in a mixed type I-type II GaAs/AlAs quantum well structure. The spatial electron-hole separation via a G-X-G electron transfer is detected in a time-resolved, non-degenerate pump and probe experiment. The time-constant for the spatial G-X-G electron transfer is determined to about 30 ps and is governed by the low density of final G states. © 1992.
