Abstract :
This paper presents the triode behavior of a gated nanodiamond vacuum field emitter array and its application in signal amplification. The triode feature is demonstrated with the observation of gate modulation on the emission current induced by the anode field. The emission characteristics are studied by considering the resultant electrical field on emitters, confirming the gate modulation effect. The voltage gain is examined, showing a reasonable value of 6.7 at the operating current of 50 μA. Higher gain is attainable at elevated operation currents.
