Fig. 1

a Top view (up) and side view (down) of the crystal structure of 1T-CrTe2. The orange (brown) balls represent the top (bottom) Te atoms, and the dodger-blue balls represent the Cr atoms. b Pseudo-3D topographic STM image (Vb = 2 V, It = 10 pA) of CrTe2 films. The thicknesses of the films are marked. c, d Atomic resolution of the HAADF-STEM (c) and iDPC images (d) of the side view of 2 ML CrTe2. e EELS quantification analysis along the red line in c, demonstrating that the chemical stoichiometry of Cr and Te is 1:2 at the green-shaded region. f, g Atomic resolution of the STM image (Vb = 0.1 V, It = 85 pA) of 1 ML CrTe2 (f) and its FFT image (g). Inset of (f) shows a zoomed-in view (1 × 1 nm2) of the ML CrTe2. The periodicity of the 2 × 1 structure is marked. The yellow circles in (g) mark the 2 × 1 superstructure of the Te lattice. h Atomic resolution of the STM image (Vb = −25 mV, It = 10 pA) of 2 ML CrTe2.
