The junction formed by the combination of a P- type & N-Type material in known as PN jn diode. It is used as a switch as well as a rectifier.
diode is unipolar
another name for diode is "pn" junction.
no....is n't
zener diode
A simple pn-junction diode is the common example of a electronic device.
I cannot think of any, but a pn junction is a part of a diode and has a rectifying properties.
the material in which using for doping is already neutral.,,so the pn-junction diode also neutral........
We use pn junction diode in rfctification as a rectifier becase it allows current to flow in one direction only, i.e. in forward biase only , and stop current to flow in reverse baised. thats why we use pn junction diode in rectification.
semiconductor diode with out a pn junction.
There are 2 type of biasing in PN junction didoe Forward biasing Reverse biasing
The resistance of a forward biased pn junction is zero.
The difference between the pn-junction diode and the zener diode is that the pn-junction diode is used for rectification while the zener diode is used for rectification and stabilization. Also, the zener diode can function in the breakdown region while the pn-juntion diode can not function in that regime.
