Poly-Diamond Gated Field-Emitter Display Cells
A microchip containing gated field-emitter display (FED) cells is designed and fabricated using vapor-deposited ptype polycrystalline diamond films and employing an integrated circuit (IC)-compatible diamond film technology on oxidized 4in Si wafers. Current–voltage (I V ) data, measured in a diode configuration at 10 6 torr, show Fowler–Nordheim (F–N) field emission behavior. A 1 4 pixel diamo...
متن کاملSecondary-electron emission from hydrogen- terminated diamond
Diamond amplifiers demonstrably are an electron source with the potential to support high-brightness, highaverage-current emission into a vacuum. We recently developed a reliable hydrogenation procedure for the diamond amplifier. The systematic study of hydrogenation resulted in the reproducible fabrication of high gain diamond amplifier. Furthermore, we measured the emission probability of dia...
متن کاملEffect of gases on the field emission properties of ultrananocrystalline diamond-coated silicon field emitter arrays
We performed studies of electron emission from ultrananocrystalline diamond ~UNCD!-coated, ungated silicon field emitters as a function of in situ exposure to various gases during current versus voltage and current versus time measurements. The emitter arrays were fabricated by a subtractive tip fabrication process and coated with UNCD films using microwave plasma chemical vapor deposition with...
متن کاملHigh-power terahertz radiation emitter with a diamond photoconductive switch array.
A photoconductive switch-arrayed antenna with a chemical vapor-deposited diamond film was developed to generate high-power terahertz (THz) radiation. With this device, an electric field stress of 2 x 10(6) V/cm can be applied to photoconductive gaps because of the high breakdown threshold of diamond and the overcoated gap structure for the prevention of surface flashover. This level of field st...
متن کاملSecondary electron emission measurements on synthetic diamond films
During the electron irradiation of synthetic diamond films, three successive regimes are encountered as a function of the electron dose: (1) a reduction of the downward band bending of energy levels at the sample surface because an excess of secondary electrons leaves the sample; (2) the creation of an internal electric field in which secondary electrons drift to the surface, leading to an appr...
