How Does A Diode Works

Diodes have two many applications across the electronic history and theory. An integral part of any electronic device in this blog we will explore the inner workings and applications of the diode. In great detail basically a diode is a one-way valve for electricity let’s take a look at the internal structure.

The dialogue is made of a semiconductor suggests that god pierce does not have any free electron put the silicone used here is not pure one part is don’t with and type in your ID and the other party’s don’t with the type of purity. 

So at the end side of the diode we will have free electrons and it the piece aside we will have big search for electron something very interesting happened at the junction of the diode be abundant electrons on the inside have a natural tendency to migrate to the whole that are available side show the inside battery is slightly negatively charged and the inside battery is slightly positively charged. 

You can see the depression region that is created certified any further natural migration of electrons in short it feels a potential barrier for electron flow if you apply an external power source across the i want to power source will attract the electrons and holes electricity flow is impossible in this case this condition is known as a reverse bias of the diode. 

You can see that the wig of the region increases here however if you connect positive terminal of the power source to the side of the diode the situation is quite different assume that the power source has been forwarded to record the barrier potential you can immediately see that the electrons will be pushed away by the negative terminal.

When the electrons cross the potential barrier they will be drained of energy and will easily occupied the holes in the what do the attraction of the positive terminal.

Please select rod can jump to the hose nearby in the region and flow through the external circuit this is known as the forward by saying of a diode simply put a diet acts like a one-way valve for. 

The electricity no let’s very the input voltage and study the direct response to it reversed voltage explain you can observe an under select the flow than the forward condition up to zero point seven volt you will find an electricity flow right after crossing his barrier potential.
