  • SYSTEMS AND METHODS FOR UNIVERSAL DEGENERATE P-TYPE DOPING WITH MONOLAYER TUNGSTEN OXYSELENIDE (TOS)
    Publication number: 20210328021
    Abstract: Disclosed are compositions and methods of semiconductors including tungsten oxyselenide (TOS) as a p-type dopant. The TOS is formed by introducing a single layer of tungsten diselenide (WSe2) to a semiconductor and subject the tungsten diselenide to a room-temperature UV plus ozone process. This process forms a TOS monolayer, which can be used as a universal p-type dopant for a variety of different semiconductors. Suitable semiconductor materials include, for example, graphene, carbon nanotubes, tungsten diselenide, and dinaphthothienothiophene (DNTT).
