Four‐wave mixing in modulation‐doped GaAs quantum wells under strong magnetic fields

Journal Article (Journal Article)

Time‐resolved four‐wave mixing is used to study electron scattering in modulation‐doped GaAs quantum wells in high magnetic fields up to 8T. A strong increase in dephasing times in strong magnetic fields is observed and attributed to a decrease in the scattering rates relative to zero field. An early time signal in high magnetic field is found, which is due to a polarization interaction process. A strong enhancement of the signal at the absorption edge is measured which is attributed to the Fermi edge singularity. Copyright © 1995 WILEY‐VCH Verlag GmbH & Co. KGaA
