Abstract

A large anisotropy in the spin dephasing times for the different in-plane directions of [0 0 1] quantum wells has been predicted in calculations by Averkiev and Golub [Phys. Rev. B 60 (1999) 15582] for systems with both Rashba and Dresselhaus spin-orbit fields. Here, we present time-resolved Faraday rotation measurements performed in the Voigt geometry on a high-mobility 2D electron system grown ...
