Field Emission Ultramicrometer
Review of Scientific Instruments, 1966A simple, contact free, ultrasensitive distance and displacement measuring instrument has been investigated. Experiments demonstrate that the instrument is capable of operating at spacings as small as a few hundred angstroms. Calculations indicate that distances of 10−3 to 10−6 cm and less can be reproduced to within about one part in 105.

Spike cathode for field emission
Physica Status Solidi (a), 1972A cathode plate with outgrowing spikes may serve as a field emission source for electrons. An estimation is presented for the field concentration according to a regular array of spikes. Spike cathodes have been produced from a semiconductor matrix containing needle-like metallic inclusions by etching-off a matrix layer.

Development of field emission displays
Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 2004Field emission displays (FED) are drawing attention as one of the most promising flat panel displays. Currently, the development stage of Spindt-type FEDs with Mo emitter is close to an end. The monocolor Spindt-type FEDs are being supplied to the market, and the color FEDs are ready for mass production.

Journal of Applied Physics, 1962
The vacuum requirements to obtain stable field emission cathodes are discussed. To keep the average work function of a tungsten emitter constant, the total pressure of all chemically active gases should not exceed 10−14 Torr. To minimize ion bombardment of the emitter surface the helium pressure should be reduced by ion pumping even with tubes made of ...

Progress in Surface Science, 1993
Abstract The first experimental evidence of the existence of electron states localised on a clean metal surface was available to us since 1967 in the form of the well known Swanson-Crouser hump in the energy distribution of electrons field-emitted from the W(100) plane, although it took some time before its interpretation as such, in 1976, was ...

Field emission, field ionization, and field desorption
Surface Science, 1994Abstract A brief description of the essential features of the theory of field emission, field ionization, field desorption, and the field emission and field ion microscopes is presented. The principal applications of field emission including work function and surface diffusion measurements, and a brief sketch of the theory of diffusion are also given.

Field Emission in a Magnetic Field
Physical Review, 1963An expression for the field-emission current in a longitudinal magnetic field is derived in the zero-temperature limit. Two cases are considered, corresponding to constant Fermi energy (A) and constant electron density (B). In both cases the calculated current density contains an oscillatory contribution periodic in $\frac{1}{H}$, as well as a term ...
