Abstract
Anisotropic spin dynamics of two-dimensional electrons in strained n-InGaAsAlGaAs (110) quantum wells (QWs) is investigated by a time-resolved Faraday rotation technique. Strong anisotropy of the relaxation time for the electron spins in parallel (τ∥) and perpendicular (τ⊥) to the QWs is observed (τ⊥ τ∥ ∼60) at 150 K as a result of the enhanced D'yakonov-Perel' (DP) spin relaxation mechanism. At 5 K, an anisotropic feature of the spin relaxation time is also observed in the presence of in-plane magnetic field, suggesting that the DP mechanism is effective for low-temperature spin relaxation.
