Performance Limits of Monolayer Transition Metal Dichalcogenide Transistors

The performance limits of monolayer transition metal dichalcogenide ( MX<sub>2</sub>) transistors are examined with a ballistic MOSFET model. Using an ab initio theory, we calculate the band structures of 2-D transition MX<sub>2</sub>. We find the lattice structures of monolayer MX<sub>2</sub> remain the same as the bulk MX<sub>2</sub>. Within the ballistic regime, the performances of monolayer MX<sub>2</sub> transistors are better compared with those of the silicon transistors if a thin high-κ gate insulator is used. This makes monolayer MX<sub>2</sub> promising 2-D materials for future nanoelectronic device applications.
