A method of forming two-dimensional transition metal dichalcogenide sheets, the method comprising:
- adding a cross-linking agent to an activating agent to form a solution;
- mixing a two-dimensional transition metal dichalcogenide with the solution to form a mixture;
- adding a cleaving agent to the mixture;
- stirring the mixture comprising the cleaving agent to form one or more contiguous sheets of transition metal dichalcogenide;
- removing any particulate matter;
- and
- exfoliating the one or more contiguous sheets of transition metal dichalcogenide by exposing the one or more contiguous sheets of transition metal dichalcogenide to electromagnetic radiation to form a plurality of two-dimensional transition metal dichalcogenide sheets.
