Fig. 1: Preparation and characterization of PtTe2 NSs.

a Schematic illustration showing the fabrication of atomically thin PtTe2 NSs with different vacancy structures. b Digital photograph of the PtTe2 crystals on a millimeter-grade paper. c XRD patterns of bulk PtTe2 crystals and exfoliated PtTe2 NSs. The standard XRD pattern of PtTe2 (JCPDS # 18-0977) is shown as a reference. d AFM image of atomically thin PtTe2 NSs. e HAADF-STEM image of few-layer PtTe2 NSs. f High-resolution HAADF-STEM image of few-layer PtTe2 NSs and the corresponding structural model of PtTe2. Inset on top shows the intensity profile corresponding to the blue line. g HAADF-STEM image and the corresponding elemental mapping images of exfoliated PtTe2 NSs.
