Abstract

We report our theoretically investigation on the spin-orbit coupling and g-factor of the X-valley in cubic GaN. We find that the spin-orbit coupling coefficient from sp3d5s tight-binding model is 0.029\,eV{\AA}, which is comparable with that in cubic GaAs. By employing the kp theory, we find that the g-factor in this case is only slightly different from the free electron g-factor. These results are expected to be important for the on-going study on spin dynamics far away from equilibrium in cubic GaN.
