Abstract

By implementing Pauli's spin-orbit (s/o) coupling and Darwin's relativistic correction, we study how relativistic terms affect the Schrödinger picture of electrons in a 2D quantum dot (QD). The competition between electron confinement and Pauli's s/o coupling produces a novel shell structure at Ω0 = 4mc2/ℏ, with stroke, and the inclusion of these relativistic terms is strictly restricted in the Schrödinger picture to ω < Ω0.
