Classification of Semiconductors (Intrinsic/Extrinsic, P-Type/N-Type)

While strange at first glance, knowing the classification of semiconductors will help you understand what they are and why they act the way they do. We discuss what's happening at the molecular level in the crystal lattice of the semiconductor and the difference between undoped, or intrinsic semiconductors and doped, or extrinsic semiconductors.

This five minute video was much helpful than my two hour lecture! Thank you

[sapphireblue]

OH MY GOSH THANK YOU SO MUCH!!! I really liked the way you explained things—it was short, concise and easy to understand. I also liked how organised this was and the visuals really helped as well!! Tysm and I hope you keep doing this.

I WAITED FOR THE TOAST TO POP! But great video! really helping me with my education :D

[aliceb]

This was so useful for me! I'm studying for my finals and I usually find physics really hard however this video really made it easier for me to digest the information since I was more invested. Thank you so much 😭🙏🏻

Hello Sir,
I am so thankful that I found this video because during this pandemic all that matters is self study .

You explained really well 👍
Thankyou Sir .

[aathi]

holy shit bud! this video was worth it!
THANKYOU!

[shabanoasif]

You explain very well. Thanks a lot for this

[ayushverm]

thank you si muuch sir for this video love from india

[XStealthZeikonX]

Brilliant summary, this is gonna help a lot for an assignment <3

[miireux_._]

That was AWESOME!!! I was struggling with p type

[SAURAVSINGH-mrmq]

Thanks a lot, tomorrow is my exam and I'll bang each and every question related to this topic. You are really a very good teacher 💯🙌💯🙌💯

[yunsishui]

very clear and helpful video. Thank you so much

[lakshmanank]

This is really so much helpful I was really confused with the concept, this video cleared all my doubts, thank u so much 😊

[STP]

Thank you so much, sir. great explanation

[beyzaskates]

THİS İS AWESOME!! thank you a lot. i really loved the video and the visuals. it makes it easier to understand. Keep up the good work!!

[muqaddasminhas]

Video is very awesome and thanks for sharing your knowledge with us ;)

0:34 and 1:50 then 2:56 That's cool! Just FYI (to help viewers) also now _(for trivalent P-Type as in vs pentavalent N-Type), _ Cl doping of Se2Sn (CMOS), so see Van der Waals contacts _(pertaining to Schottky junction/barrier as special case of a p-n-Junction)._

[DeepakSharma-pbtz]

Well Explained. Please make more videos .

[omarhabib]

Firstly, thank you much for your effort and your simplicity explanation, but I need to know something: as we know the intrinsic semi-conductor the p=n=ni; so if I want to convert it to p-type or n-type, how much should I dope with a donor whether with electrons or holes

[esthereuticterra]

Thank you so much, this video really does help me a lot to understand much better. Please continue making these educational videos because I NEED SO BAD :'D
BTW, I have liked your video and subscribed to your channel!
