Characterization of type-II Dirac semimetal PtTe2. a, b Schematic drawing of type-I and type-II Dirac fermions. c, d Side and top views of PtTe2 crystal structure. Green balls are Pt atoms and red balls are Te atoms. The unit cell is indicated by black dashed line. e Bulk and projected surface Brillouin zone onto (001) plane. Red dots (labeled as D) mark the positions of 3D Dirac points. f Raman spectrum measured at room temperature. g XRD of PtTe2 measured at room temperature. The inset shows the picture of one single crystal with a few mm size. h LEED pattern taken at beam energy of 70 eV
