The field emission in the alternative electric fields

Ultramicroscopy, 2007
We obtained a growth of the emitting points and a considerable increase in the emission current in the regime of alternative power supply for initially polished flat metal surfaces. Formed surfaces demonstrate sufficient field emission current stability in vacuum from 10(-4) to 10(-6)Torr and good tolerance and maintainability of field emission ...

Collector dependence of field emission in the Scanning Field Emission Microscopy

2021 34th International Vacuum Nanoelectronics Conference (IVNC), 2021
We have performed density functional VASP calculations of a carbon covered tungsten surface under the presence of an electric field F directed away from the surface i.e., pushing the electrons into the surface. We have found that under the presence of this field the extrapolated to the surface straight line which represents the increase of the vacuum ...

Field Emission in a Magnetic Field

Physical Review, 1963
An 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 ...

Spike cathode for field emission

Physica Status Solidi (a), 1972
A 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.
