Comparative analysis of frictional behavior and mechanism of molybdenum ditelluride with different structures

Figure 3 from “Comparative analysis of frictional behavior and mechanism of molybdenum ditelluride with different structures” by Lina Zhang et al.: Atomic-scale friction maps of MoTe 2. (a) Mapping of friction signal of 1T′-MoTe 2. (b) Reciprocal lattice obtained by 2D FFT on (a). (c) Atomic-level stick–slip map obtained by FFT filtering of (a). (d) Unit cell structure of 1T′-MoTe 2. (e) Friction profile extracted along the blue dashed line in (c). (f) Mapping of friction signal of 2H-MoTe 2 . (g) Reciprocal lattice obtained by 2D FFT on (f). (h) Atomic-level stick–slip map obtained by FFT filtering of (f). (i) Unit cell structure of 2H-MoTe2. (j) Friction profile extracted along the blue dashed line in (h). NANOSENSORS PointProbe Plus PPP-LFMR AFM probes were used.

Two-dimensional (2D) transition metal dichalcogenides (TMDCs) have layered structures with excellent tribological properties. * Since the energy difference between hexagonal-molybdenum ditelluride (2H-MoTe2) and distorted octahedral-molybdenum… Read More »Comparative analysis of frictional behavior and mechanism of molybdenum ditelluride with different structures
