(a,b) The optical images of exfoliated single-layer and few-layer 1 T´-MoTe2 on a 285 nm SiO2/Si substrates. The thicknesses of the flakes are labeled. (c) The top view crystal structure of single-layer 1 T´-MoTe2. The zigzag metal chains, a-axis and b-axis are labeled. (d) The side view unit cells of 1 T´-MoTe2. (e) The high-resolution TEM image of few-layer 1 T´-MoTe2, where the direction of Mo-Mo chain is represented by a white double-headed arrow. (f) The selected electron diffraction image of 1 T´-MoTe2 flakes top-viewed from the [01-1] zone. (g,h) The representative 1 T´-MoTe2 and 2H-MoTe2 Raman spectra of 1-layer, 5-layer, and bulk.
