The Schottky effect or field enhanced thermionic emission is a phenomenon in condensed matter physics named after Walter H. Schottky. In electron emission devices, especially electron guns …

2023年6月19日 · The Schottky effect is defined as a reduction in the energy needed to remove electrons from a solid surface in a vacuum when an electric field is applied. This boosts …

Schottky effect, increase in the discharge of electrons from the surface of a heated material by application of an electric field that reduces the value of the energy required for electron emission.

This effect, discovered by Schottky, which depends on the probability fluctuations of electron emission from a filament, has been measured over a considerable range of conditions in …

This is called the "Schottky effect", and the resulting emission regime is called "Schottky emission". In 1923 Schottky suggested (incorrectly) that the experimental phenomenon then …

2022年7月11日 · Using a quantum mechanical calculation, we investigate the fundamental limitations of the Schottky emission (SE) model for its applications to electron injection into …

A Schottky barrier, named after Walter H. Schottky, is a potential energy barrier for electrons formed at a metal–semiconductor junction. Schottky barriers have rectifying characteristics, …

The meaning of SCHOTTKY EFFECT is the increase of the thermionic current in a vacuum tube with the increase of the applied potential between the cathode and anode due to a lowering of …

The Schottky effect or field enhanced thermionic emission is a phenomenon in condensed matter physics named after Walter H. Schottky. In electron emission devices, especially electron …

The measurements made under the conditions in which the Schottky effect should appear, i.e., in two electrode tubes with no appreciable space charge, show some striking deviations from the …
