Abstract:
A new field emission triode structure with carbon nanotube(CNT)cathode called back-cathode is proposed.In this triode structure,a glass substrate with an array of holes is used as the cathode plate.The carbon nanotube emitters are printed around the holes on the cathode electrode.The gate electrodes are fabricated on another substrate which is mounted below the cathode substrate.Because a high anode voltage is applied,the electric field produced by the anode voltage can penetrate into the CNT cathode area.A negative voltage is applied on the gate electrode to control the emission current from the CNT cathode.The electrical field distribution and electron trajectories have been simulated,and the modulation feasibility and working modes of the structure have been discussed.
