Abstract
CURRENT FIELD EMITTER ARRAYS HAVE ACHIEVED VALUES OF NORMALIZED TRANSCONDUCTANCE (97 S/cm2) AND AVERAGE ELECTRON CURRENT DENSITY (1 kA/cm2) THAT EXCEED THE LIMITS OF GRIDDED THERMIONIC CATHODES BY ORDERS OF MAGNITUDE. THE POTENTIAL APPLICATION OF FIELD EMETTERS TO TERAHERTZ, MICROWAVE, AND MILLIMETER-WAVE SOURCE TECHNOLOGY, HOWEVER, IS LIMITED BY THE LIFETIME OF THE EMITTER. IN THIS PHASE I PROGRAM, ULTRAMET PROPOSES TO DEMONTRATE THE FEASIBILITY OF FABRICATING LANTHANUM HEXABORIDE (LaB6) MICRON-SCALEFIELD EMITTER ARRAYS HAVE THE POTENTIAL TO BE OPERATED AT LOWER GATE VOLTAGES, THUS EXTENDING LIFETIME AND/OR INCREASING CURRENT DENSITY.
