Description
An overview of recent theoretical and experimental studies
of optical orientation and spin dephasing of electrons in
n-type quantum well structures is presented. It is shown
that the electron spin dynamics in high-mobility quantum
wells drastically differs from that in low-mobility
structures and is highly sensitive to the quantum well
crystallographic orientation, details of scattering, and
external fields. We discuss the dynamic coupling of the
in-plane and out-of-plane spin components caused by
scattering asymmetry [1], the anomalous behavior of the
Hanle effect in high-mobility quantum wells [2], spin
orientation by linearly polarized optical pulses [3] and
spin dephasing and diffusion [4] in (110)-grown quantum wells.
