a Schematic view of 1T-PtTe2. b Large-scale STM image of the PtTe2 polycrystalline film (1500 × 1500 nm, V = 1.5 V and I = 80 pA). c STM image exhibits some contaminants present at the upper edge on the surface of the PtTe2 crystal (600 × 600 nm, V = 1.5 V and I = 60 pA). d STM image showing atomic structure of PtTe2 in a defect-free area with an interatomic distance of 4.0 ± 0.03 Å (4 × 4 nm, V = 0.7 V and I = 300 pA). e, f STM images of some defects on a polycrystalline PtTe2 film. e Empty states STM image of the PtTe2 film (20 × 15 nm, V = 0.85 V and I = 185 pA). f Filled states STM image of the PtTe2 film (20 × 15 nm, V = −0.85 V and I = 185 pA).
