internel potentiel of PN junction?? so complicated
homojunction PN (not polarized), externel potentiel difference applied = 0 Volt .
i should demonstrate the equation: e*Vbi + Eg + ( Ec - Ef ) + ( Ef - Ev) = 0
Given: Vbi= internel potential
Eg= energy gap
Ef = Fermi energy level
Ec= Energy of conduction level
Ev= Energy of valence level
then i should deduce, that if the junction are so dopped that : Vbi = Eg/e
____________________________________________________________________________
Ive try a lot to solve the first equation, but i couldn't find the solution. what I've found it that Vbi must equal Zero, and that's impossible cause .
hope someone know how to solve that.
