Room temperature spin relaxation in GaAs/AlGaAs multiple quantum wells
RS Britton, T Grevatt, A Malinowski, RT Harley… - Applied physics …, 1998 - pubs.aip.org
We have explored the dependence of electron spin relaxation in undoped GaAs/AlGaAs
quantum wells on well width confinement energy at 300 K. For wide wells, the relaxation rate
tends to the intrinsic bulk value due to the D'yakonov–Perel DP mechanism with momentum
scattering by phonons. In narrower wells, there is a strong dependence of relaxation rate on
well width, as expected for the DP mechanism, but also considerable variation between
samples from different sources, which we attribute to differences in sample interface …
