@Bunu Kala Shrestha, you're most welcome.

Chan Kok Keong - 2020-04-08

I put my heart and my soul into Physics after watching this channel.
Nothing's boring in this universe if you tell a good story.

Physics Videos by Eugene Khutoryansky - 2020-04-08

I am glad to hear that my videos have made such a big impact. Thanks.

Physics Lover - 2020-04-09

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

Marik Zilberman - 2020-04-10

I think you meant 'if you tell a good story'.

Chan Kok Keong - 2020-04-10

@Marik Zilberman You’re right! It sounds more correctly.

Sean Dafny - 2020-04-16

YES !!

Chadzilla IV - 2020-04-08

Our lord and saviour has posted once more

Chadzilla IV - 2020-04-17

@Araf H Raaj Damn dude I guess you're just smarter than every intellectual who has studied any of the topics you're talking about for their whole lives day in day out contemplating. You must be really smart to come up with a viewpoint shared by millions of people who don't know what they're talking about

Araf H Raaj - 2020-04-17

@Chadzilla IV, Yes, I can realize that you are smarter than 8 billion people in the world because you live in the world of fantasy... Come on... Except pure one heavenly book, you will find lots of mathematical error in all other books. Do you think God doesn't know a simple math? Come to the true path... You will never ever be able to see light if you remain in the dark and will not understand what millions of people are talking...

Brijendra Mishra - 2020-04-18

@Araf H Raaj you follow your path. And let others follow their path.

Hochspannung Lebensgefahr - 2020-05-13

People in the comments really ignored the video and started discussing god's existance .
No one cares if there is a god or not , just don't be an idiot and enjoy your life

Dmytro Dieiev - 2021-02-07

😂

Apoorv Bagal - 2020-04-08

Stay safe Eugene!We need you

Physics Videos by Eugene Khutoryansky - 2020-04-08

Thanks. I hope you stay safe too.

akh345 - 2020-04-08

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!

Physics Videos by Eugene Khutoryansky - 2020-04-08

Thanks for the compliment about my video.

Sean Dafny - 2020-04-16

Physics Videos by Eugene Khutoryansky Eugene u are truly amazing

Heisenberg's Dog - 2020-04-09

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.

Physics Videos by Eugene Khutoryansky - 2020-04-09

Thanks. I am glad you like my visualization.

GStar - 2020-04-08

This is what I wanted!
Please make a video for LASER also if possible

Rykehuss - 2020-04-08

and MASER

Physics Videos by Eugene Khutoryansky - 2020-04-08

Thanks. Lasers are on my list of topics for future topics.

Chris - 2020-04-08

I thought the same thing before reading your comment! Would love to see his style of explanation for laser/maser

Physics Lover - 2020-04-09

O yes laser. Seriously I also wanted that video as soon as possible .

William Dye - 2020-04-09

It helps me to think of the bigger picture: the goal is to control the flow of electricity with... electricity. Mechanical switches are slow, so we need a device that can change states between conducting well and conducting badly, and the change of state must be set using only electricity.

KB Tek - 2020-04-08

Physics is one of my favorite subject 😍😍😍 animation that you are making is great

Physics Videos by Eugene Khutoryansky - 2020-04-08

Thanks for the compliment.

darrylkid - 2020-04-16

5:10 So just to get this clear, the sporadic presence of holes gives the appearance of moving positive charges although the protons stay fixed?

Physics Videos by Eugene Khutoryansky - 2020-04-16

Yes, that is correct.

Jithin Paulson - 2020-05-14

Protons and holes are unreleted... holes are just representations of absence of electrons. Pls correct me if im wrong..

Tess Del Rio - 2020-08-26

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!!!

Physics Videos by Eugene Khutoryansky - 2020-08-26

I am glad my videos have been helpful. I plan on making additional videos on semiconductors and the other topics. Thanks.

Nothing\ - 2020-04-17

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.

Physics Videos by Eugene Khutoryansky - 2020-04-17

Thanks. I plan to make more videos dealing with semiconductors in the future, using this format.

Dante Ramirez - 2020-04-10

Physics Videos by Eugene Khutoryansky - 2020-04-08

Thanks for the compliment. Yes, this is on my list of topics for future videos.

jkinkamo - 2020-04-10

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.

Physics Videos by Eugene Khutoryansky - 2020-04-10

Glad you liked my video. Thanks.

Taylor Langley - 2020-11-02

Thank you this video helped me understand so much vs just looking at diagrams in the textbook.

Cosmos San - 2020-11-25

Eugene please upload a vid on why breakdown occurs in diode in reverse bias

Christopher Kebenei - 2020-04-09

Physics Videos by Eugene Khutoryansky - 2020-04-09

Thanks.

RustyBolts - 2021-02-01

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...

First Commenter - 2021-03-16

This is a very superb video.
Hopefully can see more other type of semiconductor devices.

subramanian ganesan - 2020-04-25

Great to see a video from you after a long time..... May your service reach new heights ...

Qaxeem Butt - 2020-04-09

Can you please add a topic of quantization of energy in you photoelectric effect video and can we have wavelengths less than plank length . I heard that when the wavelength getts smaller than the plank length the light is converted into mass. So please also explain thr mass energy relation in terms of quantum mechanics in your photoelectric effect video . Tell us what are these fundamental constants of plank length ,plank time, plank energy and plank temperature.

Nondescript - 2020-10-09
