摘要: A gated single carbon nanotube field emitter with magnetic focusing is proposed and simulated using a parallelized Poisson’s equation solver, coupled the ray tracing of electrons, on an unstructured tetrahedral adaptive mesh. The for electrons can be achieved by vertically downward (−Bz) through use either external solenoids or permanent magnets around field-emission array. simulation results, assuming uniform inside unit, are compared those conventional tetrode-type emitters electrostatic structure. results reveal that design promise much higher emission current, while smaller spot size at anode. In addition, magnitude applied gate voltage in range 60–120V shows little influence electron-beam diameter method also possibly reduce complexity fabric...
