Abstract

In this work, we report the effect of the spin-orbit (SO) interaction on the band structure of TlInSe2. Calculation was performed by implementing density functional theory (DFT) method. Our results show that SO interaction is significant for two high symmetrical point (τ, T) and line (κ, A) of Brillouin zone in the band structure and negligible changes was observed in the bands near the Fermi level. The maximum SO splitting is ∼0.9 eV.
