Abstract
The transport of polarized electrons in photocathodes based on highly strained semiconductor superlattices is studied experimentally and theoretically. In the experiments, the electron emission from the photocathode excited by a femtosecond laser pulse is studied by time-resolved measurements. The response time and the spin relaxation time are experimentally determined. The photoresponse of the photocathodes is calculated, and the results are correlated with the experimental data. A conclusion regarding the partial localization of photoelectrons in the superlattice is drawn.
