摘要：

Based on first-principles calculations within density functional theory, we find that Pb adlayers can induce a giant Rashba spin splitting in the quantum well states of an underlying Bi2Se3 film. As the thickness of the Pb adlayers varies, the distance between the Pb adlayer and the Bi2Se3 film, the charge density at the interface, and the binding between the Pb adlayers exhibit an oscillatory behavior due to the quantum size effects, which in turn modulates the magnitude of the Rashba spin splitting of the quantum well states in the Bi2Se3 film.
