amante pensanta: Isn’t that the truth? I’ve been an engineer for over 45 years. I’ve lost count of the number of times that I’ve encountered various technologies and asked “Who thinks of this stuff?”
I am a fan of logical unsurprising progression. Learning about logical unsurprising progression that occurred over hundreds of years within the course of a few months in a college class does in fact appear very surprising to me. I'm glad you have a galaxy brain that already knows everything; maybe you can tell us how to solve our world's problems, if it's that uninteresting.
Of course, no one came up with the idea overnight, and certainly not from scratch. It's the result of continuous progress over time with many trails and errors, until we come to the current point.
You're the best in explaining even very complex things in non-complicated manner. I need to refresh my not-often-used knowledge every couple of years - and you can do this in matter of minutes. Kudos. 👌
I took a full year of electronics theory and semiconductor device fabrication a decade ago and wish this had existed then. The way Ben explains it is just so straightforward and easy to understand.
After many university lectures, different youtube videos, this is the first time that i actually understand PN Junction. You have such an awesome way of explaining things. If you're not a university professor, then it would be a big loss for many students
I have been trawling through you tube videos and web articles all week searchng for a really good elementary explanation of how the semiconductor (and specifically the diode) works, but until now without finding anything really satisfying. Always there has been some defect - some were too superficial, some too technical, some skipped over essential steps in the explanation (leaving you asking in exasperation ... "yes, but WHY???"), some contained obvious mistakes and inconsistencies. This one was perfect. Good graphics, all the steps in the explanation present, and narrated by someone who speaks clearly and at just the right speed. Many thanks.
Just had a braingasm. Years, years, years, I have tried to understand this to no avail. Thank you so much for this. Better education for free online than when I tried to learn it at university.
Thanks a lot! After 40 years I've found clear and understandable explanation how it works! (I'm not working in this field, but I was a computer fan in early 80s and I love all this staff like ZX80, 6502 and so on). Your views are great!
Perfectly explained .I did electronics in college and even our teacher had 2 degree, one in electrical engineering and next in electronics ,somehow he couldn't do it so well as this youtuber. From all the digital electronics tutors on the you tube, he is N1.And by the way who are those 26 ,who disliked the video? I see probably some Nobel holding physicians or just junkeez.
Brilliantly explained, Im studying civil eng. but having to do a unit on engineering materials and I've been struggling to get my head around electrical currents and the like but you video explained it in terms I can understand. Many thanks
you just explained in 15 minutes what my university teacher took like 30 minutes to explain and you somehow made it sound interesting and not boring. Also, i'm spanish and the funny thing is that i understood way better this explanaition (not my native language) rather than my teacher's (my native language) Outstanding
This is so much better explained than in many text books, thank you so much! And I applaud you for correctly explaining current to flow from - to +, I'm always getting so confused when textbooks try to make things easier by simply not telling how it actually works (which is also how school works btw :) ).
Chemistry has always been a struggle for me but I love computer engineering as a whole. This video was so clear with its presentation, I actually have some confidence in understanding how this works. Thank you so much.
You are REALLY good at explaining this stuff! I've watched a couple of videos and am now subscribed. Your calculator tutorial immediately made sense even though every other explanation I've seen didn't.
I took like 12 credit hours worth of electronic materials science courses in college that I just barely got through, and this 16 minute video explained it better than all of them combined.
Some people explain with as if we're too dumb which further confuses me with all their abstract example in an attempt to simplify. You my friend dignified my brain, and this video has helped me understand semiconductors
I never feel any reason to regret the time I spend watching your videos. You are a superb teacher. Thank you for the electronics engineering lesson. I have my degree in electronics, by the way, albeit in more of a technical manner, but this was still priceless.
You are one of the best teachers in this world. Please,. just please if possible, make a series of computer science lessons, from very ground up theory to let everyone actually know what is going on. I watched a ton of CS related videos, I could say, you are at least one of the best, if not the best best best, I really doubt you are an earther, you must be alien, with such a high level knowledge of everything, what a splendid learning experience. Please, teach this world a better CS lesson, we really need a teacher like you. I know making videos is very hard and time consuming, just, if possible, this world need this! (PS: I watched your 4 bit adder video, really learned a lot, I want to learn everything from you, teacher :)
Wow, awesome explanation @Ben. I love your videos, especially this one. About four years ago, when i was freshman Physic college, i asked a senior electrical engineering about why we used diode symbol that has reserve current flow. Very glad i have found the answer in the end of this video. Thank you.
Thank you..I seen all your videos. You are really really awesome!! I actually want to say you that it completely changed my notion towards electronics, networking and computers. Very very very well taught..Thank God for finding you and this channel..Looking forward to you and more.
Thank you so much for this video, my chemistry teacher did a terrible job at explaining semiconductors to us and my test is tomorrow. I feel way more confident after watching this video!
Man, thank you! I have a presentation tomorrow to explain transistors, but i didnt understand this from the teacher. I found this video when i came across the transistor video, and it helped me allot. so again thanks man :D
Incredible explanation! Hopefully, you will have more videos up explaining about various subjects on engineering. This video is not only clear and concise, it teaches us at more of a "human" level rather than expecting everyone to have a PhD to fully understand.
Very good Ben. I was just plodding along in my CS50 course learning C, then Googled "C assembly comparison" out of curiosity, found your video on Comparing C to machine language, then your breadboard computer video, then I googled 8 bit computers, found your website, and finally a link to this video, which is much more fun than when I learned semiconductors during my Physics degree ten years ago, because now I have a context. I actually dropped out of that degree, but it's funny how life takes you full circle sometimes! I look forward to looking at all your work! Your videos help me learn much faster than by reading a book, so thank you. Should probably get back to my course now :))
This is great! Thank you for the wonderful explanation. I definitely benefited from this. I am working on a Chemistry project in engineering college, and this really gave me a head start on where to go with it. Thank you again.
This explanation locked everything into place for me! My teacher didn't addressed the flow of "electrons" as opposed to the flow of "current" in the charges diagram explanation the way you did. Thank you very much!
That was very well explained! I had an electronics course last semester but never actually understood the physics of semiconductors and transistors. Very helpful videos.
You're the guy who made understand why the holes are moving. Thank you Ben. Let's say the 1st atom have hole. The 2nd atom will give one electron to the 1st atom, causing the 2nd atom to have hole. Now, The 3rd atom will give one electron to the 2nd atom , causing the 3rd atom to have hole. So we can see that the hole is slightly moving from 1st atom to 3rd atom, that is how the hole move.
Thanks for the awesome explanation! I wouldn't say that it's "incorrect" to think of the circuit flowing from + to -, it's just not considering the flow of electrons, as we'd intuitively imagine, like flowing water. Instead, as you explained, the "holes" in the P-type can be described as a positive voltage and so the circuit has a figurative positive voltage flowing from + to -.
u rock man !!!!..this was one of those topics which just went over my head whenever i tried to understand it and u hav made it super simplified to understand thanks a lot...
I love your videos and a big fan of your work. I would just really appreciate it if you could give a brief overview in the beginning of the video of the material being discussed or post a short version and a long version. Because if the viewer has some background they may want to skip some parts or get bored when you repeat yourself, although the flow may be just perfect for someone with no background in the topic.
Stunningly well explained!! I've read about this in a few books now, and was >sort-of< getting it, but this brought it all together very, very clearly. Thank you, Ben!
I wish I had your explanations 45 years ago when I was starting my electronics engineering training. Some of the ways you explain things make the forehead-slappingly obvious.
I watch a few videos about this and they was very similar, but yours is very helpful cuz you try to explain thing not making a 6 mins video on youtube, Thank you
Ben, this is such a cool explanation of how this works. I mean, I knew we basically named "positive" and "negative" backwards and our notion of current flow is still colloquially described basically backwards of how the electrons actually move … but I had no idea how N-type and P-type material worked or anything. Holes in my brain are now filled. Which means I have some free electrons to send to other people.
The amount of respect I feel right now for the guys that first came up with this idea is immense...

Beautiful work man, such a good explanation!
WHOA!! I quit combat arms 2 years ago to focus on my engineering studies and then I see you in this video!
How ironic HAHAH!! How are you man??
Kevin Haha not too bad man! Awesome that you are doing engineering and by the looks of it you're doing electrical :P Enjoy it!
Omg you replied! Yes I am doing electrical!!
Are you doing electrical engineering too?
Kevin Yep! In my third year :)
@Rakesh Mehta good times haha, lots has changed since then!

If there was more high quality videos like this available, I wouldn't need school and lectures.
Excellent! Breakthrough stuff for me, as no one that I know of has explained -- visually and verbally -- this material so clearly. Thank you, Ben!

Excellent explanation. As a CS major, I didn't get dow to the molecular level of chips. Thanks for this it really helps.
No one ever has explained with so much clarity yet ! Thank you very much friend👍🙏

The clearest exposition I have come across on this subject.
Excellent! The only time someone has actually explained how this works! Thank you.
I’ve heard this information before, several times, but this is the first time I understood it. Thanks.
You have an incredible ability for teaching. This kind of cleanly-produced, highly visual guide is really the perfect way to learn things.
Thank Mr Eater I found your explanataion to be both clear and better giving a sense of the physical phenomenon.
I never feel any reason to regret the time I spend watching your videos. You are a superb teacher. Thank you for the electronics engineering lesson.
I have my degree in electronics, by the way, albeit in more of a technical manner, but this was still priceless.

so again thanks man :D
The first five seconds of the video scales quickly. This is a group of four transistors… now here’s a BILLION
Thank you so much for supporting the gratis pursuit of knowledge
this is so helpful, was totally confused about how semiconductors work and now it seems so simple and clear. Thank you and keep making such videos !
Some people are just better in explaining things.. You are one of them!
Incredible explanation! Hopefully, you will have more videos up explaining about various subjects on engineering. This video is not only clear and concise, it teaches us at more of a "human" level rather than expecting everyone to have a PhD to fully understand.
I took an entire university course on this and understood nothing, passed the test by pure guesswork. With this video, I finally get it.
Ben, thank you once again for a great video. I enjoy learning from your videos. You have a very effective teaching style for me.
Wow finally someone who really explained this in details, it's all so clear now! Thank you!

Great video as always. I would have taken electrical engineering back at college if I had had access to videos like this 30 years ago.
Very nice graphic explanation of the n and p properties and behavior. Good job.
You are such an absolutely excellent teacher
Thank you! For a while I've been looking for a video that clearly explains how a semiconductor works, and this finally did the job perfectly.
That was super interesting, thanks. The amount of work and knowledge that’s into creating today’s computers is astounding.
You're the guy who made understand why the holes are moving. Thank you Ben.
Let's say the 1st atom have hole.
The 2nd atom will give one electron to the 1st atom, causing the 2nd atom to have hole.
Now,
The 3rd atom will give one electron to the 2nd atom , causing the 3rd atom to have hole.
So we can see that the hole is slightly moving from 1st atom to 3rd atom, that is how the hole move.
By far the most clear explanation on this topic!
best explanation I've found about semiconductors on youtube!
You are so good at explaining.
I could be the the next Tesla if you were my teacher 30 years ago.

Great explanation! I always thought of the diode symbol as the arrow pointing at a wall to indicate that current does not flow in that direction.
Thanks!
