Non-zero bandgap, great mobility in nanoscaled dimension
Example: transition metal dichalcogenides, black phosphorus, metal monochalcogenide, etc.
Quantum transport simulations employ non-equilibrium Green's function and Poisson's equation
Hamiltonians are based on tight-binding, maximally localized Wannier function, and density functional theory
Other Research Interests
Quantum transport simulation with consideration of issues in digital IC (e.g. dark silicon, thermal issue, etc.)
