摘要：

Current theory [Fiz. Tekh. Popluprovodn. 20 (1986) 178; Sov. Phys. Semicond. 20 (1986) 110] indicates that the D'yakonov-Perel' (DP) mechanism is unable to cause spin dephasing in quantum well (QW) with [110] growth direction. We point out that this is no longer true when the many-body inhomogeneous broadening effect of the DP term is taken into account. Based on our many-body theory [J. Supercond. 14 (2001) 245], by solving the kinetic Bloch equations, we show that the DP term contributes to the spin dephasing in (110) QW. The spin dephasing is also compared with that in (100) QW.
