PN Junction Diode working in Tamil

PN JUNCTION DIODE WORKING PRINCIPLE OF OPERATION:
To explain the properties of a pn junction, p-type and n-type semiconductor are suitably joined.
Keep in mind that n-type material has a high concentration of free electrons while p-type material has a high concentration of holes.
Therefore, at the junction, there is a tendency for the free electrons to diffuse over to the p-side and holes to the n-side.This process is called diffusion.

The combination of these holes and electrons create a new region between the two layers. This region is called “depletion layer”.
Only inside this, there is positive charge on ‘n’ side and negative charge on ‘p’ side. Because of this a potential is produced in this layer which is called “barrier potential”. The barrier potential in directly related to depletion layer. The barrier potential opposes the flow of majority carriers through the junction and it aids the flow of minority carriers.
For both of these opposite effects, no charge carriers will flow through the junction at normal condition. The potential difference across a pn junction can be applied in two ways namely, forward biasing and reverse biasing.

Thank You for watching

Sir, First of all, Thank you so much, sir... I am a Kerala Technological University student, I had a backlog for EDC which kept me away from getting my degree, I've tried 5+ attempts to clear the exam without understanding the basic concepts (The concepts weren't clear in most of the notes which I referred) it was in my last attempt I came across your videos, thank god for directing me to your videos sir...The results came last day, and I finally completed my Degree !!! Once again Thank you so much sir for your extraordinary contribution to the lives of students like me... Again Thank God for giving you to us...

happy engineers day sir ...i m a mechanical engineer ..your classes are very useful for my competitive exam preparations . thanks

[abiramiraja]

Sir...this type of explanation i have never seen in my career...

[sathyanvenkatesan]

Good lecture sir with a proper explanation and the doubt which I had raised is completely a lots of love from this student😇

[vinothkumars]

Intha maathiri enakku oru physics vaathi kedaikkala.🧐🧐🧐
Semmaya puriyathu sir.
Thank you 🙏

[jimmuluj]

Ur teaching is awesome sir.keep doing this sir.thankyou, 🙏

[Harshini-zxno]

Easily understandable & clear explanation
Thank you very much sir 🙏

[rajalingam]

What a nice explanation sir? For many years I'm trying to study this subject but I will forget it as I couldn't understand properly. Even now I thought of avoiding this subject for trb preparation. But after seeing ur clear cut explanation started seeing your upcoming videos. Thank you very much sir.
