Abstract

In time-resolved Faraday rotation experiments, we have detected an in-plane anisotropy of the electron spin-dephasing time SDT in an n-modulation-doped GaAs/Al0.3Ga0.7As single quantum well. The SDT was measured with magnetic fields of B1 T, applied in the 110 and 11¯0 in-plane crystal directions of the GaAs quantum well. For fields along 11¯0, we have found up to a factor of about 2 larger SDT ...
