Just a little extra info to help anyone else to remember the two types: P-type stands for "positive" type because the added hole is positively charged, and N-type for "negative" type because the added electron is negatively charged!
It does blow my mind when I think about the geniuses that figured this stuff out. Difficult enough to understand when explained, let alone discovered as a new concept!
I have been looking for easy to understand explanation for electronics chapter, for upcoming exams most of videos on these topics were full of tangential information but thank God I came across your channel, your videos are helping me a lot. Keep up the good work... 👍👍👍
trust me there ain't any crisp explaination then this one.....thank for resolving such a broad topic in so easy way...already subscribed and liked the video
Thanks! A year ago, I was given a really good explanation of how energy bands are formed but now I'm forgetting the particulars. I'll have to go through my old notes and see if I wrote it down when Dr. Campbell was discussing it with me.
Hi a Great thanks to you, you are really doing a Great job, Anyone those who wants to know what is electronics can see your wonderful videos, May God bless you. Continue your work a Heartfelt congratulations for your work.' God's Grace i found your videos
It is a weird concept. We treat "holes" as a particle, but really, it's just a pathway that an electron can jump from hole to hole, meaning that they can move (via the holes) but don't move as quickly or as easily as if they were completely free from specific atoms and instead had joined the "sea of electrons" where they tend to be able to move easier because they're *completely free. (Not actually completely free but it's easier to think of it in absolutes)
@@CircuitBreadSince conductors do not have this current due to said 'holes', does it change anything? Semi-conductors can generate a normal current from electrons as well as from holes, but conductors can only generate current from the free electrons in the conduction band.
Yep, I agree! We're working through a couple different series (including Circuits 1) and once Circuits 1 is done, I plan on moving directly into Circuits 2.
WOW THIS AND ALL THE OTHER VIDEOS OF THE SERIES ARE REALLY AMAZING!!! VERY INFORMATIVE WITH HIGH QUALITY ANIMATION!!! TYSM! THIS WILL HELP A LOT WITH STUDIES!!! 🤗🤗😊😉👍
Thank you for the feedback! We've used a few different software applications for animations over the years but I think this was done in the Adobe suite with After Effects.
Thank you for the explanation. Just one question, where are the electrons that leave the extra holes in P-type and where are the holes left by the extra electrons in N type?
I'm not sure if I understand the question. The extra holes in the P-type are there because the dopants have one less valence electron than the substrate, so there aren't any additional electrons. The reverse is true for the N-type. There aren't additional holes left lying around just because there's an extra electron. That's what makes them special. Let me know if I'm not actually answering the question!
Good work! In the LED case, are the areas of the n-type and p-type material have the same thickness and what is the reason of putting the p-type material on the top?
Thanks! We actually have a video that explains a bit more in-depth about how all this works and also mentions why the p-type material is on the top (spoiler alert - it's what actually emits the photons, so you don't want to block it) - ua-cam.com/video/No8PZsLnjZU/v-deo.htmlsi=qoODt41tleXruRXn As for the thickness difference between the two, I'm actually uncertain. I think in the construction process, the p-type is built on top of the n-type substrate but I don't know if there's a need for them to be different thicknesses.
Thank you for the easy to understand explanation Sir.... But I have a doubt... How can Boron having three valence electrons bond with four silicon atoms....And also I didn't understand how a hole gets formed in this case or in this bonding process of boron and silicons...
Great question! We have a few videos that talk about how diodes work at the semiconductor level. The first one is here: ua-cam.com/video/btOIDQeMrMg/v-deo.html Hopefully that answers your question!
Hello sir, would you like to suggest an author book for power electronics, which will help to build basics of this subjects. Your video has helped a lot but i need to understand some other topics related to power electronics too Thank you
Sorry, I don't really have any recommendations for power electronics textbooks. Perhaps someone on our Discord channel would have some recommendations?
will electrons stays there in conduction band when they overcome band gap and leaves valance band or they will lose their energy sooner or later and emits a photon and go back to their valance band?
Eventually they will lose their energy and either emit a photon or energy in the form of heat. We go into more detail about how the semiconductors work in practice further along in the semiconductor playlist we put together. Hopefully it helps!
Hi Majid! We did a three part series on exactly that - check out the first one here: ua-cam.com/video/btOIDQeMrMg/v-deo.html Then the rest should pop up after watching this one.

Gallium has the incorrect atomic number when you show it, just so you know
These videos are very simply explained. Keep up the good work
Just a little extra info to help anyone else to remember the two types: P-type stands for "positive" type because the added hole is positively charged, and N-type for "negative" type because the added electron is negatively charged!
omg thankyouuu
No, P and n type of semiconductors both are neutral. Yes you can use this to remeber but it's not true... (I guess so)
I don't understand all you said, but you said it flawlessly. Humans are friggin smart.

i didnt find a channel explaining things in such a compact and easy way.... and then i found this. Thanks a lot :)
You're welcome, Anushka!
I am an Arab
You are really a genius
It made it easier for me to study this material
Thank you, I'm glad this helped!

Binge-watching your vids. It's really informative and inspiring as an aspiring electronics engineer in the future. More power in your channel! ^_^
Thanks Chris, I really appreciate all the kind feedback!
Awesome ! really simple explained
Thanks Hesham!
Thank you for your video, it's very useful, but I have a question: How can a"hole" conduct electricity? Thank you!
It is a weird concept. We treat "holes" as a particle, but really, it's just a pathway that an electron can jump from hole to hole, meaning that they can move (via the holes) but don't move as quickly or as easily as if they were completely free from specific atoms and instead had joined the "sea of electrons" where they tend to be able to move easier because they're *completely free.

@@CircuitBread I'm understand. Thank you very much!

super helpful! thumbs up from Japan
Awesome, glad it helped!
Thanks you so much for very useful video, i can easily understand about semiconductor.
Happy to help!
aww just flawless
this video is so clear and helpful. Thanks a lot
Amazing. Fundamentals first.
Thanks!
You teach better than my teacher 🔥👍
Great explanation ❤️
Usefull for my presentation
Thanks so much!
The way he hits the B in bismuth at 2:05
Thank u so much.
thank you, really helpful for my 12th grade exam tomorrow!
I'm glad they're helpful, good luck on your exam!
wow excellent video
It will be lovely if you make a series about circuit 2 where it's all about ac signal
Yep, I agree! We're working through a couple different series (including Circuits 1) and once Circuits 1 is done, I plan on moving directly into Circuits 2.
this guy is better than my professor

The element Boron is represented by B, not by Bo
Dang it... we obviously missed that during the review. Thanks for letting us know!

i believe that PMOSFETS work based off the introduction of trivalent particles and NMOSFETS work based off the introduction of pentavalent particles

Sir how does p nd n junction work in solar pannel?
With the semiconductor, how does one turn the electricity flow off & on?

What is dopping
How does a p-n junction work?
Hi Majid! We did a three part series on exactly that - check out the first one here: ua-cam.com/video/btOIDQeMrMg/v-deo.html Then the rest should pop up after watching this one.
when we making semiconductor work what do we call that process
Doping? When it's being made? Or biasing? Which is when it's being used.
@@CircuitBread the answer is biasing I just finish my work thank you
Awesome!
p*n=ni^2 physical significance
is there a reason you didn't mention aluminum when listing trivalent atoms?
Only in that the list isn't exhaustive, no particular reason that aluminum wasn't mentioned.

I hoped that the bread would come out,Disappointing 😂
😂 Someday... someday we'll post one video that has the bread pop up at the end. And we won't tell anyone...
No semiconductors= No more humans walking around like zombies and ignoring their crying children because they are texting.
Less children are ignored now than there were no semiconductors.
Not a free electron, but a loosely bonded electron.
