Theoretical calculation of type-II Dirac cone in PtTe₂. a Calculated band dispersion along the in-plane direction S-D-T and out-of-plane direction A-D-Γ-D-A through the Dirac point. b Three-dimensional plot of the electron and hole pockets at the Dirac point energy. The electron and hole pockets touch at the Dirac point D. c–e Contours of electron and hole pockets at −20, 0, + 20 meV around the Dirac point energy in the k _x–k _z plane. The electron and hole pockets touch at E _D and clearly separated at E _D ± 20 meV
