Sir Eugene make videos that are so spiritual and soothing for my heart and mind. We had forgotten about the beaty of this universe but sir Eugene changed your thinking and made us see the beauty of universe in his animations
Ha ha ha... You people make God anyone anytime you want. But the truth is, Only true creator is one and He is not atom or molecule like us but He can create it. It will make sense because science proves an atom can not create another atom. Whole life you waste by reading huge unnecessary books but don't have much time to read the summary of 4 major religious book to judge which one is correct... Do you think Creator of the universe will do nothing if people tell lies without research?
@@arafhraaj603 Damn that's crazy dude too bad I did all that and I found direct evidence that there wasn't a creator, you might need to look a little harder. You probably haven't read enough theology.
Having experienced a traumatic childhood and lousy education; I am one of many recovering ignoramuses or egnorolics even, cause most get turned off physics and math for life. Thanks to brain plasticity and the net, we can recover. Cannot thank Eugene and team enough for their great service to humanity, now and for generations yet unborn...
The genius of this video is the depiction of the rising and lowering electron energy levels with the differing 1) N or P doping; 2) voltages applied across the diodes; 3) direction of applied voltages; and 4) location of contacts allowing current flow. For those of us who are right hemisphere and cerebellar thinkers, this makes it very memorable. It just makes sense to see the electrons having to struggle to move up steeper or less steep energy level “hills”. Well done.
Semiconductors were a tough thing to get my head around in electronics class, the professor was great, but couldn't explain the physics. This will likely be my new mental model. Thanks!
@Felix Carpio i have found that if I have a good mental model of *how* something works, rather than remembering facts, I can run rings around the people who only use tote memorization. Don't remember it, understand it. Additionally, you're much less likely to be able to use devices/tools outside of their intended uses if you don't actually understand them. With a deeper understanding, you can make better predictions about untested situations. Lastly, it's simply fun to understand the world as well as you can.
The music on your videos personally keeps me more concentrated and curious throughout the length of the videos. Thank you so much for this extraordinarly instructive content!
You are super creative Eugene! The best intuitive video ever watched about the PN junction diode and NPN transistor. keep creating this kind of content to solidify the base of upcoming science students.
Прекраснейшая визуализация вопроса, долго меня мучавшего, спасибо!) Я не изучал физику на серьезном уровне, но всегда было интересно как все устроено, спасибо за ваш канал!
Thank you so, so much. These are the best animations and explanations I have come across for physics. What I previously thought were just dull words on paper have turned into beautiful new ways of thought and exploration. You are a hero and an inspiration.
I had a lecture about semiconductors at university and I learned about it at school but nothing gave me a picture about its functionality as nice as this video! Really happy I found this channel.
This video had helped me sooooooooooo much when I tried to understand this chapter at school because gravitational potential energy is something every large organism can intuitively understand and it is a perfect analogy so these animations are absolutely amazing at explaining the PN junction and transistors.
After long time I got notification of your video sir. But as usual the quality of content is top class again video is so much informative and helpful. Thankyou
I love the quantized aspect of the visualization. Between the energy levels, but also between the available positions the electrons and holes can take in space.
im passing chemistry because of you 😭 thank you so much for your time and energy. you've helped inspire my passion for physics more than i could've ever imagined. now im looking at material scientist grad school programs !! would love more semi conductor videos, maybe colligative property videos, thermochemistry, or similar phase change chemistry topics from a physics perspective. take care!!!
This is absolutely amazing!! I wish this video existed a few years ago when I was studying this. I wanted to point out that this electron level stacking visualization thing shown by Eugene is MUCH deeper conceptually than it may seem. Say, see some electrons "falling down" at 9:05? this is how LED works!
I would just like to inform you your channel is the only one on youtube I have watched all videos because the way you illustrate your animations is far better than the other ones.
I love the new graphics format you've used for this video. I would definitely like to see more videos in this style. Especially a video about the different mechanisms of electrical breakdown.
I was watching videos about electromagnetism from playlist "Electricity videos in order", and all of them were like five years ago. And then I stumble across this video, that was posted only two weeks ago. I feel lucky to see it now when it is relevant to me.
Ohh thank you so much for this video! I´m studying semiconductor physics and ill have an exam soon. Your videos are amazing, they help me understand physics and see the beauty of it. Best regards!!
And these are the people who deserves respect and admiration. He fights to keep the scientific society alive. Our scientists, engineers, architects, Doctors and of course those humble works like delivery, food service, mail man, repair man are all equally useful. We learned at last that every job should be respected.
I wish I could support your channel and your awesome videos! I love this channel Never disappointed me with content! Videos like this make me feel like I've found some gold mine! Just thank you🤗
Great to see a video from you after a long time..... May your service reach new heights ... ...... It would be nice if you put more videos on Nuclear Physics.....
THANK YOU SO MUCH!!! this is exactly what I wanted I could never visualize why the base current was always lesser in comparison to the collector current thus made my day.
You are so excellent. We love your videos all over the world, it´s united fascinations. Greetings from Vienna.. Stay healthy and thank you for hours of beautiful physics lessons.
Thanks, this is an essential lecture indeed! For the newcomers as well as for the folks from the valve era. The latter ones (like me) have probably forgotten the "voltage model" of the bipolar devices and instead are dealing only with the current model. And that does not explain enough the base region behaviour. Back in the 80's they taught us valves first thus probably easier to jump directly to the PNP-bipolars (e.g. 12AX7A => AC128). Were this video available that time it would have been much easier to understand the working of a transistor, i.e. without the valve analogue. I truly recommend this video, especially the requirement for a thin P-type base region biased to conduct (at 11:00) in order to get the device working.
Very,very Good. More than an explanation of electronics, it is a course of english, to me ,here from Brazil.I anderstood all she said, with this measured and perfect pronunciation. thank you.
@@EugeneKhutoryansky I can see how the electrons move from n-type to p-type materials in different sites. In the textbooks, they show the hole migration by the movement of the positive charges which denote holes. Here, could we show the hole migration from p- type to n- type materials with the movement of the protons?
Long ago, a prophecy was told. A man with such high intellect would appear every other century for a few minutes only, to grace us with the light. Rejoice fellow men, for this day has come, and Eugene is back!
Electrons fill holes in energy bands and you fill holes in basic physics for engineering students who were to inmature to pay attention in the early stages of their careers, you magnificent bastard, you did it again, this is what internet is supposed to be for, thank you.
