(color online) Structures of PdTe₂ thin films grown on bilayer graphene (BLG). (a) Schematic crystal structure of PdTe₂ of side (bottom panel) view. [(b), (c)] STM topographic images (1.7 V, 80 pA) of epitaxial PdTe₂ films on bilayer graphene at (b) low coverage and (c) high coverage. Layer thickness is indicated in each panel. (d) Atomically resolved STM image (−780 mV, 1.6 nA) showing a terrace step. Inset displays line profile across the step. [(e), (f)] XPS results of bulk PdTe₂ (black curves) and epitaxial PdTe₂ films (red curves). (e) Te 3d core level spectra of bulk PdTe₂ and as-grown films. Characteristic peaks have the same positions at 572.5 eV (3d_5/2) and 582.9 eV (3d_3/2). (f) Pd 3d spectra of bulk PdTe₂ and as-grown films. Peak positions at 336.9 eV (3d_5/2) and 342.1 eV (3d_3/2) are also the same.
