Field Emitter Array RF Amplifier Development Project, Phase 1, Option 1
Abstract
Key Idea: (1) Develop field emitter arrays with a cutoff frequency above 1 GHz, total current greater than 5 mA, and 5 A/cm squared current density with the gate electrode potential less than 250V. Demonstrate these characteristics for greater than 1 hour lifetime; (2) Reduce capacitance and increase transconductance of field emitter arrays to improve frequency response. Focus on development of tall emitter columns to minimize capacitance. Evaluate low work function materials and metals as emitter surface coatings, reduce gate dimensions, and improve tip sharpening to increase transconductance. Fabricate large arrays with dense tip spacing to increase total current; and (3) Examine various test methods to permit characterization of more devices per test cycle
