Electronic and optical properties of topological semimetal Cd(3)As(2)
Using ab initio density functional theory the band structure and the dielectric function of a bct Cd(3)As(2) crystal are calculated. We find a Dirac semimetal with two Dirac nodes k(±) near the Γ point on the tetragonal axis. The bands near the Fermi level exhibit a linear behavior. The resulting Di...
