"Using tungsten telluride nanowires, they created bundles of wires deposited on a flat substrate. These were exposed to vapors of chalcogens like sulfur, selenium and tellurium. With a combination of heat and vapor, the initially separate threads in the bundles were successfully woven together into narrow, atomically thin nanoribbons with a characteristic zigzag structure. By tuning the thickness of the original bundles, they could even choose whether these ribbons were oriented parallel to the substrate or perpendicular"
