First-principles band structure results for Na3Bi. a Schematic representation of Na3Bi lattice structure under uniaxial strain. b Band structure without strain. c–e Enlarged band structures near the Γ point along the k z -axis for strain value c 0%, d −3%, and e −7%. The Dirac points are indicated by the red arrow in b and by red dots in c, d
