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 ...
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 ...
These simulation results are shown in Supplementary Information Fig. 4a. The retention times could then be estimated at different operating temperatures by using the Arrhenius equation to estimate \({k}_{1}\) as a function of temperature as...
It has been noticed that in one-dimensional scenario, the Schr \\ddot{m{o}} \\ddot{m{o}} dinger equation satisfied by the created particle (anti-particle) near the event horizon, can be reduced to a differential form which is exactly identical with that obeyed by an electron ...
(4) accurately tracks a more computationally intensive ordinary differential equation (ODE)-based device model. In Supplementary Fig. 7, we show the “action” Ax(T) corresponding to different signal types with different magnitude and energy. The results show that Ax(T) is monotonic with respect...
According to Good and Müller [15], the Fowler-Nordheim (FN) current density J through silicon dioxide is dependent on the temperature T and the corresponding electric field F and can be calculated from the following equation:J(EF,T)=4πqmsckTh3∫0φexp(−42mox(χ−E)33ℏqF)ln[1...
