Researchers from Tokyo Metropolitan University have made tungsten disulfide nanotubes which point in the same direction when formed, for the first time. They used a sapphire surface under carefully controlled conditions to form arrayed tungsten disulfide nanotubes, each consisting of rolled nanosheets, using chemical vapor deposition.
The team’s technique resolves the long-standing issue of jumbled orientations in collected amounts of nanotubes, promising real world device applications for the exotic anisotropy of single nanotubes.
The study is published in the journal Nano Letters.
