OPERA simulations and evaluations of field-emission characteristics of a triode electrode structure were performed in order to develop a field emitter using carbon nanotubes (CNTs). The field emitter OPERA simulations included various parameters, such as the height and the structure of the gate electrode and the field-emission voltage (anode and gate voltages). A model of the triode electrode structure was constructed for the OPERA simulations. The parameters of the field emission were selected using the results of the OPERA simulations. A CNT field-emitter with a triode electrode structure was developed using the obtained parameters, and its field-emission characteristic were evaluated.
