Transition-metal chalcogenide (TMC) nanowires, which are one-dimensional structures having three-atom diameters and van der Waals surfaces, have been reported to possess a 1D metallic nature with great potential in electronics and energy devices. To mass produce TMC researchers in Japan have demonstrated a wafer-scale synthesis of highly crystalline transition-metal telluride nanowires by chemical vapor deposition. The technique enables formation of either aligned, atomically thin two-dimensional (2D) sheets or random networks of three-dimensional (3D) bundles, both composed of individual nanowires. These nanowires exhibit an anisotropic 1D optical response and superior conducting properties. The findings not only shed light on the controlled and large-scale synthesis of conductive thin films but also provide a platform for the study on physics and device applications of nanowire-based 2D and 3D crystals…read more.
