Abstract

We use time resolved four wave mixing to study electron scattering in modulation doped GaAs quantum wells in high magnetic fields up to 8 T. We find a decrease in scattering rates relative to the zero field behavior. The four wave mixing signal shows a strong enhancement at the lowest Landau level which we attribute to the Fermi edge singularity.
