Diode Ideality Factor

Does the diode ideality factor can be lesser than 1? or very close to 1?

ID and VD are the diode current and voltage, respectively

q is the charge on the electron

n is the ideality factor

k is Boltzmann’s constant

T is temperature in Kelvin

• Where did the equation come from? What are D, S, q, VD, n, k and T? – Transistor Aug 6 '18 at 13:41
• @Transistor Looks like the Shockley Diode Equation... or was that something you wanted the OG to figure out? Lol woops – user103380 Aug 6 '18 at 14:18
