Quantum effects on electronic transport in semiconductor nanostructures are studied by calculating the conductance, using a nearest-neighbor tight binding Hamiltonian and a recursive Green's function approach. The effects of structure geometry, electrical potentials, impurities, and magnetic fields on the conductance of nanochannels, quantum wires, and dots are explored.

By improving the understanding of charge transport fundamentals in such structures, these theoretical studies support the future development of ultra-small, ultra-fast electronic devices.

Professors Yong Joe and Mahfuza Khatun lead condensed matter physics groups that also include Professors Feng Jin, Tony Cancio and Eric Hedin and teams of graduate and undergraduate students.
