Abstract

The effects of Rashba spin-orbit interaction (SOI) on the energy levels of parabolically confines quantum dot were analyzed. The spin-polarized electronic states were obtained in a weakly confined dot, when SOI was greater than a critical value of the SOI strength. It was observed that in high magnetic fields, the spectra of low-lying states exhibited features of Fock-Darwin levels and Landau levels. It was also observed that the effective SOI in the system was decreasing with increasing magnetic field and confining potential of the dot.
