Ab-initio Prediction of Conduction Band Spin Splitting in Zincblende Semiconductors

Abstract

We use a recently developed self-consistent GWGW approximation to present systematic \emph{ab initio} calculations of the conduction band spin splitting in III-V and II-V zincblende semiconductors. The spin orbit interaction is taken into account as a perturbation to the scalar relativistic hamiltonian. These are the first calculations of conduction band spin splittings based on a quasiparticle approach; and because the self-consistent GWGW scheme accurately reproduces the relevant band parameters, it is expected to be a reliable predictor of spin splittings. The results are compared to the few available experimental data and a previous calculation based on a model one-particle potential. We also briefly address the widely used {\bf k}β‹…\cdot{\bf p} parameterization in the context of these results.Comment: 9 pages, 1 figur
