Energy levels and electron g-factor of spherical quantum dots with Rashba spin–orbit interaction

Abstract

We have studied simultaneous effects of Rashba spin–orbit interaction and external electric and magnetic fields on the subbands energy levels and electron g-factor of spherical quantum dots. It is shown that energy eigenvalues strongly depend on the combined effects of external electric and magnetic fields and spin–orbit interaction strength. The more the spin–orbit interaction strength increase, the more the energy eigenvalues increase. Also, we found that the electron g-factor sensitively differers from the bulk value due to the confinement effects. Furthermore, external fields and spin–orbit interaction have a great influence on this important quantity.
