A diode is voltage and current sensitive it follows an exponential curve and lower then .6v it is considered off and above .6v is considered on.
when a semiconductor is doped with p-type and n-type impurities, a pn junction is formed which acts as a diode and prevents the charge carriers to flow to either side of junctionpn juction diode is a semiconductor device that allows current to flow only to one direction.
diode is unipolar
another name for diode is "pn" junction.
no....is n't
there are many uses. one major use i remember is in rectification i.e convert ac to dc For switch operation
zener diode
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.
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
