A pn junction can be formed by bringing the p and n type materials together.
n-p-n and p-n-p junction diodes
that is how the p & n sides are created.
limts of operating a p-n junction
Both the p and the n are pronounced
Suppose Pk is the product of the first k numbers. P1 = 1 Pn = n*Pn-1 for n > 1 Curiously, though, when used for permutations or combinations (or for the Gamma function), P0 = Factorial(0) = 1

The built in potential in a pn junction. Due to the difference in carrier concentration between the sides of a pn junction. Diffusion potential increases with increase in doping levels.
A diode has a n type and a p type materials that's why it's called a pn-junction device
PN means pressure rating of a pipe....PN is just a symbolic representation....
PN 16 valve can withstand 5 bar pressure. I have experienced that at 7 bar it cannot hold the pressure and starts to leak.
xn=x1+(n-1)v^t and Pn=P1+(n-1)iP1
