Abstract
The anisotropic spin dephasing in (110) quantum wells (QW) from 6 K up to room temperature was investigated. It was found that intersubband scattering constitutes a new spin dephasing mechanism that is necessary to explain reduced spin lifetimes at elevated temperatures for electron spins along (110). The spin lifetime of spins perpendicular to the growth direction is about one order of magnitude shorter compared to spins along (110). The modification and total suppression of spin oscillations through anisotropic spin dephasing was also analyzed.
