(a) Side view of the layered Pt₃Te₄ crystal structure, with alternate PtTe₂ and Pt₂Te₂ layers stacked along the vertical direction. Panels b and c show the top view of the Pt₃Te₄ surface with (b) Pt₂Te₂ and (c) PtTe₂ terminations, respectively. (d) LEED pattern obtained at an energy of 100 eV. (e) Band structure and the corresponding density of states. (f) Raman spectrum acquired using a laser with 632.8 nm wavelength. (g) Theoretical phonon dispersion in the primitive unit cell along with the phonon density of states. (h) Resistivity as a function of temperature, for four different values of the magnetic field, ranging from 0 to 9 T.
