WebJul 18, 2011 · The Fowler-Nordheim equation. The basic formulation of quantum mechanical tunneling of conduction electrons from a plane metal surface into vacuum was conceived by Fowler and Nordheim (Fowler & Figure 1. Potential energy of an electron as a function of its distance x to the surface (schematic). WebThe Fowler-Nordheim equation in solid state physics relates current, work and electric field strength to determine field emission. It has two parts: an equation for field emitted current density, and the equation for total current. It is named … Fowler–Nordheim-type equations Introduction Fowler–Nordheim-type equations, in the J-F form, are (approximate) theoretical equations derived to describe the local current density J emitted from the internal electron states in the conduction band of a bulk metal. The emission current density … See more Field electron emission, also known as field emission (FE) and electron field emission, is emission of electrons induced by an electrostatic field. The most common context is field emission from a solid surface into a See more Field electron microscopy and related basics As already indicated, the early experimental work … See more The energy distribution of the emitted electrons is important both for scientific experiments that use the emitted electron energy distribution to probe aspects of the emitter surface physics and for the field emission sources used in electron beam instruments such as See more Field electron emission, field-induced electron emission, field emission and electron field emission are general names for this experimental phenomenon and its theory. The first … See more Field electron emission has a long, complicated and messy history. This section covers the early history, up to the derivation of the original Fowler–Nordheim-type equation in 1928. In retrospect, it seems likely that the electrical … See more Introduction The next part of this article deals with the basic theory of cold field electron emission from bulk metals. … See more The original theoretical equation derived by Fowler and Nordheim has, for the last 80 years, influenced the way that experimental CFE data has been plotted and analyzed.
