Numerical analysis of carbon nanotube field emitter arrays with embedded electron beam focusing structure
A new structure of triode-type carbon nanotube-field emitter arrays (CNT-FEAs) is proposed whose extraction gate is surrounded by CNT emitters. 3-dimensional numerical calculations of electrostatic potential for the proposed CNT-FEA was carried out using the finite element method and the results were compare with those of conventional CNT-FEAs.
