Abstract:
For circular quantum dot (QD) with account of the Razhba spin-orbit interaction (SOI) an exact energy spectrum is obtained. For the small SOI constant the eigen functions of the QD are found. It is shown that application of radiation field with circular polarization lifts the Kramers degeneracy of the eigen states of the QD. Effective spin polarization of transmitted electrons through the QD by radiation field with circular polarization is demonstrated.
