Constrained patterning of orientated metal chalcogenide nanowires and their growth mechanism.

ABSTRACT: One-dimensional metallic transition-metal chalcogenide nanowires (TMC-NWs) hold promise for interconnecting devices built on two-dimensional (2D) transition-metal dichalcogenides, but only isotropic growth has so far been demonstrated. Here we show the direct patterning of highly oriented Mo₆Te₆ NWs in 2D molybdenum ditelluride (MoTe₂) using graphite as confined encapsulation layers under external stimuli. The atomic structural transition is studied through in-situ electrical biasing the fabricated heterostructure in a scanning transmission electron microscope. Atomic resolution high-angle annular dark-field STEM images reveal that the conversion of Mo₆Te₆ NWs from MoTe₂ occurs only along specific directions. Combined with f
