Spin-Orbit Interaction in Buckled 2D Systems


Spin-orbit coupling in 2D materials can be either extrinsic or intrinsic. An example of the former is Rashba effect, where an external electric fields results in a formation of Dirac cones. Intrinsic SOC, on the other hand, typically leads to a gap opening, as seen in Xene’s and some transition metal dichalcogenides. It turns out that for certain lattice geometries, atomic spin-orbit interaction can give rise Rashba-like dispersion without an external field. We study a lattice which manifests this behaviour using tight-binding formalism and DFT calculations.
