Fig. 2: Crystal and electronic structures of RuOCl2 monolayer.

a Lattice structure with top view in the up panel and lateral view in the down panel. b The electron localization function (ELF). The iso-values of 0 and 1 indicate complete electron delocalization and perfect electron localization respectively. c The Fermi surfaces, with the arrows indicating the electron velocities at the Fermi surfaces. d The electronic band structure and density of states (DOS). The energy at the Fermi level is set to zero. The symbol θ in the inset represents the angle between q and the x direction.
