How does the current change as doping concentration of p region increases? What I am confusing now is that i think if the concentration increases there will be more hole to cross the junction and that makes the current higher. Or I can also say that as width of depletion layer decrease, carriers can easily cross the junction. It will increase the current. However, the equation of current, ID=qA(D₂/Lpn/ND + Dn/Lan?/NA) [exp((eV₂)/KT)-1] , shows that if N_a increases, value of current decreases. Can you explain what is correct? Does current increase or decrease as concentration increase? How does the current change as doping concentration of p region increases?
