Theory of electron emission in high fields from atomically sharp emitters: Validity of the Fowler-Nordheim equation Field emission from metallic emitters is generally described by the Fowler-Nordheim [F-N] theory, which is based on a planar model of the tip with a classi... PH Cutler,J He,...
The equation determines the energy levels and probabilities of finding electrons in different regions. When an electric field is applied across a thin insulating barrier, it creates a potential difference that electrons can tunnel through. The FN tunneling probability depends on three factors: the ...
The quanti-tative evaluation of the WF values from the experimental current-voltage measure-ment is based on the Fowler–Nordheim (FN) equation which expresses the relationbetween the emission current density J, applied f i eld F and the work function ϕ.Various modif i cations of the FN ...

The functions v(y) and t(y) are useful in evaluating the Fowler-Nordheim field emission equation. The related function s(y) is used in examining the slopes of logarithmic plots of this equation. Six-place tables of v(y), t(y), and s(y) are presented for values of y from 0 to ...
场发射特性也称为Fowler-Nordheim隧道效应，低维材料中的电子在外加电场作用下穿过势垒的过程。在金属半导体异质结和重参杂半导体中，这种量子隧穿效应起着重要的作用。We derive of the tunnel probability from the time independent Schrödinger equation:[3.1.44]which can be rewritten as [3.1.45]Assuming ...
