| 中文摘要 | rashba spin splitting (rss) in biased semiconductor quantum wells is investigated theoretically based on eight-band k center dot p theory. we find that at large wave vectors, rss is both nonmonotonic and anisotropic as a function of in-plane wave vector, in contrast to the widely used isotropic linear model. we derive an analytical expression for rss, which can qualitatively reproduce such nonmonotonic behavior at large wave vectors. we also investigate numerically the dependence of rss on the various band parameters and find that rss increases with decreasing band gap and subband index, increasing valence band offset, external electric field, and well width. all these dependences can be qualitatively described by our analytical model. |
