Researchers from New York University developed a new a new manufacturing process for tungsten disulfide that resulted in highest quality ever reported for the material. The process is based on chemical vapor deposition (CVD), with some "subtle yet critical" changes.

The high-quality material provided a large energy bandgap and its charge carriers had a small effective mass. The material also exhibited strong spin-orbit coupling, which means that it may be an interesting material for spintronics.
