There are 2 type of biasing in PN junction didoe
Forward biasing
Reverse biasing
another name for diode is "pn" junction.
I cannot think of any, but a pn junction is a part of a diode and has a rectifying properties.
The resistance of a forward biased pn junction is zero.
What is the cause of reverse recovery time in a pn junction diode
When light falls on the junction of a pn junction/diode the potential barrier gets break down due to majorty of electrons flow and they release energy in the form of light.
n-p-n and p-n-p junction diodes
diode is unipolar
another name for diode is "pn" junction.
no....is n't
zener diode
This is a characteristics of semiconductor diode {pn junction}.In forward biasing here we connect p to positive terminal and n -ve terminal when external voltage is aplied in such a direction that cancels out potential barrier thus permitting current flow In reverse biasing the connection of pn junction is inverted but in this the potential barrier incresesand offers resistance to current flow but at a certain voltage current increases suddenly(the break down voltage)the zener diode works in this principle
I cannot think of any, but a pn junction is a part of a diode and has a rectifying properties.
When the pn junction is forward biased, some of the space charge is neutralized reducing the width of the pn junction.
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.
The resistance of a forward biased pn junction is zero.
