Investigation of an NEA Diamond Vacuum Microtriode Array

The properties and characteristics of vacuum microtriodes based on ΝEΑ diamond surfaces were modelled. Specifically, an ΝEΑ diamond vacuum microtriode array was investigated using electrical measurements, electron optics software, and microwave circuit simulation. Data for emission current versus applied voltage for various anode-to-cathode distances for diamond ΝEΑ surfaces was analyzed and various parameters were extracted. Electron optics software was used to determine Fowler-Nordheim and space-charge-limited DC I-V characteristics for each microtriode. Microwave circuit simulation was done to determine the behavior of arrays of these vacuum microtriodes in an RF amplifier circuit.
