Abstract :
Large arrays of silicon field emitters are being produced at MCNC for use in RF and microwave amplifiers and other high-intensity electron beam source applications. Significant levels of both total emitted current (up to 7 mA) and current density (7 A/cm2) are obtained using gate electrode potentials less than 250 V with emission efficiencies as high as 99%. Large arrays of field emitters are operated at 100% duty cycle for over 18 hours. Data from devices with 1197 and 232 630 tips are presented, along with electrical yield statistics for arrays of other sizes
