The electronic properties of Zn₃Si₂ without SOC. (a) The orbital-resolved band structures for Zn₃Si₂ monolayer (yellow: total p_z orbitals; light grey: total p_y orbitals; blue: total p_x orbitals; olive: total d orbitals). The Fermi level is set to zero. (b) Projected density of states of Zn₃Si₂ monolayer. (c) 3D projection of Dirac cone in the vicinity of the K point.
