Field Emitter Array RF Amplifier Development Project. Phase 1, Option 1
Abstract
Key ideas include development of field emitter arrays with a cutoff frequency above 1 Ghz, total current greater than 5 mA sq. cm current density with the gate electrode potential less than 250V and to demonstrate these characteristics for greater than 1 hour lifetime. We reduce capacitance and increase transconductance of field emitter arrays to improve frequency response. We focus on development of tall emitter columns to minimize capacitance and evaluate low work function materials and metals as emitter surface coatings, reduce gate dimensions, and improve tip sharpening to increase transconductance. Test methods are examined to permit characterization of more devices per test cycle.
