strongly by the SOC, especially the VBs near the Γ point. The main shape of optical properties such as the di-
electric function, the absorption coefficient and others show the similarity in both NonSOC and SOC calcula-
tions. However, the SOC causes more peaks in the dielectric function, and the shape of most optical properties is
shifted slightly by the effect of SOC. Our result is in good agreement with results from earlier experiments and
simulations.
