Abstract
We report on the dynamics of the transport processes which determine the photoresponse of quantum well intersubband IR detectors. Immediately after intersubband excitation, coherent transport is important. This process can be identified via interference effects between photoexcited carriers. The carriers are re-captured subsequently within a few picoseconds. These fast transport processes give rise to space charges, which induce an additional, slow component of the photocurrent in the ns to microsecond(s) regime.
