Seminar Abstract: 

A first-principles calculation of the emission current in a single-walled carbon nanotube electron source using the non-equilibrium Green's function and Fisher-Lee's transmission formulation to describe electronic transport through the system. The simulation results reproduce the trends observed in experimental data closely and, in particular, the current saturation behavior observed in experiments and the deviation from the Fowler-Nordheim behavior. The proposed numerical approach is useful whenever a region of vacuum is present in the device Hamiltonian, which existing commercial transport solvers do not model.
