The modified neglect of diatomic overlap semiempirical quantum mechanical method, a multiscale quantum/classical hybrid method, is used to simulate the field electron emission in single-wall carbon nanotubes. The classical analysis and quantum computations have shown that a larger separation of the anode from the emitter enhances the field electron emission
The field electron emission from extending states through a localized energy level in a phenomenological way has been discussed. The method of non-equilibrium Green function is adopted. The physical origin of the enhancement of field-emission can be understood from the potential-energy diagram. For the higher temperature, the localized level can be occupied in weaker field. Correspondingly, the transition...
Summary form only given. We have reviewed the recent progresses in simulations on the field electron emission (FE) from carbon nanotubes of physical sizes. We propose a theoretical model which reveals the origin of the low turn-on field of FE of carbon nanotubes
