- Intrinsic spin-orbit coupling leads to Dirac cone formation.
- Model aligns with DFT calculations.
- Provides microscopic understanding of spin-orbit effects.

## Abstract

We propose a novel model for including spin-orbit interactions in buckled two dimensional systems. Our results show that in such systems, intrinsic spin-orbit coupling leads to a formation of Dirac cones, similar to Rashba model. We explore the microscopic origins of this behaviour and confirm our results using DFT calculations.
