On the mobility-lifetime products in photorefractive GaAs-AlGaAs quantum wells structures determined by moving grating technique measurements

Marek Wichtowski, Ewa Weinert-Rączka, Eliza Miśkiewicz, Agnieszka Branecka


The method to determine mobility-lifetime products of photoexcited electrons and holes in semi-insulating GaAs-AlGaAs quantum wells structures is proposed. The method is based on measurements of a photoconductivity and optical investigations of a photorefractive material response in wave-mixing setup using the running grating technique.
