Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I wanted to know how the pre-exponential and exponential terms of the standard Fowler Nordheim Tunnelling is calculated to a certain value. So can anyone give the calculations of these two terms?

The FN Expression is given as

J = A.F^2.exp(-B/F)

Where J = Current Density, A = pre exponential term = q*mo/(16*pi*pi*h*mox*phi_b)

B = Exponential Term = (4/3)*[sqrt(2*mox)]*[q*phi_b]^(3/2)/(q*h_bar*F)

with due regards
