A proposal for the measurement of Rashba and Dresselhaus spin-orbit interaction strengths in a single sample
arXiv:1109.5842 · doi:10.1016/j.physleta.2012.05.027
Abstract
We establish an exact analytical treatment for the determination of the strengths of the Rashba and Dresselhaus spin-orbit interactions in a single sample by measuring persistent spin current. A hidden symmetry is exploited in the Hamiltonian to show that the spin current vanishes when the strength of the Dresselhaus interaction becomes equal to the strength of the Rashba term. The results are sustained even in the presence of disorder and thus an experiment in this regard will be challenging.
