Single tip and arrays of n-type, (100) monocrystalline silicon field emitters were fabricated with a dual-gate structure. The field at the tip can be expressed as E= beta (Vgl+Vgr), in which Vgl and Vgr are the left and right gate voltages. By applyi

An array of 812 gated Si field emitters arranged in a circular pattern with a diameter of 0.089 cm is used to bombard a 2.25 mu m thick, 220 mu m*460 mu m AlGaAs single-quantum-well, separate confinement heterostructure (SQW SCH) slab. Some of the em

Current fluctuations of a gated, n-type, (100) silicon field emitter were recorded from initial emission, through the forming process, and then cycled between low ( approximately 0.4 mu A) and high ( approximately 10 mu A) currents. After the first e

By operating the field emitter triode in the collector-assisted field emission mode, a strong dependency of the collector current as a function of emitter-to-collector distance is obtained. This property can be used in the construction of displacemen

The field at the tip of a field emitter triode can be expressed by E= beta V/sub g/+/sub gamma /V/sub c/, where V/sub g/ and V/sub c/ the gate and collector voltages, respectively. For small gate diameters and tips below or in the plane of the gate a

By positioning the gate below the tip in a vacuum triode, field emission can be initiated by the collector voltage V/sub c/ and the emission current can be modulated by the gate voltage V/sub g/. Principle of operation is demonstrated for a single-ti

A simple model that is applicable to Spindt-type emitter triodes is presented. Experimentally, it has been observed that the gate current at zero collector voltage follows the same Fowler-Nordheim law as the collector current at high collector voltag
