Spin-dependent electron single and double scattering from quantum dots and antidots

We present a theoretical study of the spin-dependent electron scattering from spherical quantum dots (antidots) embedded into III–V semiconductors. To calculate the elastic scattering cross-section we use the effective one electron band Hamiltonian and spin-dependent boundary conditions generated by the spin–orbit interaction in the structures. It is demonstrated that the spin–orbit interaction can lead to a recognizable magnitude of polarization for single and double scattering at zero magnetic field.
