Spin-orbit interaction in a two-dimensional electron gas in a InAs/AlSb quantum well with gate-controlled electron density
Year: 1998
Type: article
Abstract: We present experiments on the tuning of the spin-orbit interaction in a two-dimensional electron gas in an asymmetric InAs/AlSb quantum well using a gate. The observed dependence of the spin splitting energy on the electron density can be attributed solely to the change in the Fermi wave vector. The spin-orbit interaction parameter $(\ensuremath{\alpha}\ensuremath{\approx}0.6\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}11}\mathrm{eV}\mathrm{}\mathrm{m})$ as such does not change significantly with electron density.
