  • SUBSTRATE DIRECTED SYNTHESIS OF TRANSITION-METAL DICHALCOGENIDE CRYSTALS WITH TUNABLE DIMENSIONALITY AND OPTICAL PROPERTIES
    Publication number: 20220380934
    Abstract: A method of producing transition-metal dichalcogenide crystals includes providing a silicon substrate having a phosphine-treated surface, exposing the phosphine-treated surface of the silicon substrate to a vapor containing a transition metal, and exposing the phosphine-treated surface of the silicon substrate to a vapor containing a chalcogen. A crystal of the transition-metal and the chalcogen is formed on the phosphine-treated surface of the silicon substrate to produce a transition-metal dichalcogenide crystal by chemical vapor deposition.
