Journal of Wide Bandgap Materials, 2002
Summary form only given. Results from studies of the fabrication process and emissivity of FEAs of mold-type made of silicon carbide are presented. The gated and non-gated field emission arrays of SiC sharp emitter tips have been produced by the transfer mold technique.

Large positive and negative voltage pulses applied to field emission tips can rearrange atomic or molecular adsorbates on the tip. If this rearrangement persists when field emission is measured at a lower negative voltage, the rearrangement will alter the field emission rate, and the device will function as a switch with memory.

IEEE Transactions on Electron Devices, 1991
Triode RF amplifier structures using field emission cathodes have been investigated from both the theoretical and experimental viewpoint. The physically large experimental structure used and the theoretical calculations for that structure are described. The agreement between theory and experiment for both DC and AC measurements is shown to be very good.

1978
The two kinds of field-emission (point-projection) microscopes* were both invented by E. W. Muller(1) (Figure 14.1). The older device (1936) employs field-emission of electrons from the negatively charged tip of a very sharp needle in a vacuum by point-projection of the image onto a positively charged, fluorescent screen.

Physics World, 1997
Where would we be without the cathode-ray tube? It is cheap to make, it dominates today's display technology and it can be found behind the screen of almost all modern desktop computers. For decades this descendant of the 19th-century vacuum tube faced no serious competition.

Field emission monotron for THz emission
International Journal of Infrared and Millimeter Waves, 1997Small-signal negative conductance of a field emission monotron was calculated, which was considerably higher than that of a thermionic monotron due to strong bunching of emitted electrons in a field emission. The amplification constant of 28dB/mm is achieved at THz wave region by applying the monotron to a distributed amplifier and is sufficient to ...

Review of Scientific Instruments, 1962
An apparatus is described which measures the energy distribution of electrons extracted from solids, particularly semiconductors, by high electric fields. The energy spectra of these electrons are directly related to the location of allowed electronic states at the surface of the solid.

Field emission displays based on linear horizontal field emission cathodes
Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 1997We have developed a linear horizontal wedge field emission cathode for field emission displays. The cathode consists of a horizontal wedge with a diameter of curvature ∼10 nm. A self-aligned sloping gate is positioned at a distance of ∼10 nm above the wedge.

Field Emission and Field Ionization
1968Both the field-ion microscope and the field-emission microscope are projection microscopes, in which the image is formed by radiation originating from a sharply pointed specimen and diverging from it to strike a fluorescent screen in a vacuum chamber. In the field-emission microscope the image is formed by electrons escaping from the negatively charged

Field Emission in Doped Nanotubes
Journal of Nanoscience and Nanotechnology, 2005Doping into nanotubes is an attractive and significant way to tailor their electron transport and emission properties. This article reviews some recent experimental and theoretical advances in the studies of doping behaviors in carbon nanotubes and gallium nitrogen nanotubes, and doping effects on their field electron emission properties.
