Fig. 3: Cross-section atomic-resolution imaging of MoTe2 and WTe2.
From: Emergent layer stacking arrangements in c-axis confined MoTe2
a Magnified HAADF-STEM image of bulk MoTe2 with an overlaid atomic structure schematic. The black lines show the bridging Te-Te pairs and the red arrows represent the inter-layer shift. b, c HAADF-STEM images of bulk MoTe2 and WTe2, respectively, with overlaid arrows representing the average value of λ. d HAADF-STEM images of a MoTe2 flake exfoliated onto amorphous SiO2 with a protective carbon overlayer. The arrow magnitudes in b–d are 15 times the calculated shift. e HAADF-STEM image of the same MoTe2 flake, highlighting a stacking soliton (marked with the white arrow). λ is represented for each individual Te-Te pair. The size of the arrows correlates with the magnitude of the shift, with a nonlinear scaling to emphasize the stacking soliton; the shift magnitude is suppressed in this region. The scale bar in (e) applies to (b–d) as well.
