Hi! Just wanted to let you know that I love your videos and wishing you luck in the steps you need to take to get the next one out! And no pressure, I just wanted to pass along some encouragement and positivity today.

hi, does anyone know if the oxide layer could be created in between silicon layers. what if silicon layer are attached together encapsulant. can silicon oxide still be grown under dry conditions?

Fantastic video.

Outstanding crash course. Thanks

You managed to explain to me in just a half hour, what several years of physics and chemistry in school couldn't: how chemical bonds form, how molecules and atoms interact, and why metals conduct electricity while other materials don't. And of course how semiconductors work. I salute you, well done.

There actually are switches which work by ionizing hydrogen such as thyratrons and other types of triggered spark gaps. The resistance to ionization is actually pretty useful for preventing them from triggering when you don't want current to flow. Such devices have interesting applications like krytrons used to trigger the explosive lenses in nuclear weapons

Very good job explaining it. Wish I could make better videos to explain my Amateur science studies.

For those That prefer a mechanical analog you can look at harmonics of a guitar string and such. The video I present is another mechanical method of quantizing a system. It is one of two methods where structures can actually be produced. ruclips.net/video/wrBsqiE0vG4/видео.htmlsi=waT8lY2iX-wJdjO3 Area under a curve is often equivalent to energy. Buckling of an otherwise flat field shows a very rapid growth of this area. If my model applies, it may show how the universe’s energy naturally developed from the inherent behavior of fields. Under the right conditions, the quantization of a field is easily produced. The ground state energy is induced via Euler’s contain column analysis. Containing the column must come in to play before over buckling, or the effect will not work. The sheet of elastic material “system” response in a quantized manor when force is applied in the perpendicular direction. Bonding at the points of highest probabilities and maximum duration( ie peeks and troughs) of the fields “sheet” produced a stable structure when the undulations are bonded to a flat sheet that is placed above and below the core material.

This is an awesome video! Thank you!

very nice

As an electron, I approve of this video.

Ditto @yahyafarag5598

I only know of 3 channels that explain stuff this well without having to use dumbed-down or straight up false analogies or interpretations of the math.

respect you patience , great work thank you

Hi, i noticed you have been using a water gun that can dispense distilled water, and it honestly looks extremely useful, i have never seen anyone else use anything similar, and i was wondering if you could give me the name of it.

Woah, this video was awesome

Incredible video, thank you so much. Only thing: at 15:00 you say that an electron moving at 133 km/s could travel around the earth in a minute. i assume you meant it could travel to the center of the earth in one minute since 133 km/s × 60s = 7980km which would be enough to travel the earths radius of 6371 kilometers, while the earths circumference is about 40 000 km.

Nice video, I am waiting for the next one now. A suggestion: don't be scared of adding more technical explanations, and maths details. People may get scared but the explanation will be able to dive deeper in the imagination using harder math.

Outstanding, thank you.

I've taken several classes in Quantum Mechanics, including one involving crystal lattices/semiconductors (the "inverse lattice", "Brillouin zones," etc.). Although there is quite a bit more that can be said, this video *truly* gets the main points right.

when can we expect part two?!!!!

Very well explained. Thank you!

In any design, if any material/metal laid over photoresist and photoresist being removed the metal too will be removed, or in some cases its not.

Very clear. Great job!

You sir, are a rockstar

brilliant explanation !

Amazing explanations, awesome!

I appreciate the hard work put into this and taking the time out of your own interests to share your perspective. This is an intuitive description. Looking forward to seeing what else you describe.

Excelleeeeent!!! I’m a Chem engineer doing a PhD in Bio molecular, and this video was wonderful!! Best introductory video. It should be shown to students before starting to get deeper into details! Can’t wait for future videos.

wow this is such a good video. thank you! keep making the series, please. the animation was solid, wouldn't have guessed it's your first.

I just subbed immediately because of this video. Amazing and enlightening explanation of molecular orbital theory and semiconductors! 😄

24:10 Holy smokes did you just explain fine structure in an intuitive way??? O.o EDIT: Ah, no wait. This isn't fine structure. Fine structure is a different phenomenon.

This is really cool! Great teaching video bro

Make a machinist video please

This is an absolute S tier explanation of not only quantum mechanics, but how and why those mechanics bridge the gap between the atomic and macroscopic levels. When the two protons merging dropped the hill below the ground state I literally let out a vocal "oh my god" completely involuntarily. These kinds of topics are so far reaching in their subject matter, that even when I put serious work into researching and talking with my professors, it's very hard to walk away with an understanding that is holistic. In most situations people only explain the mechanics as they directly relate to the subject matter their teaching. My professor's explanation of semiconductors was more from a classical mechanics perspective since it was an introductory class and he just needed us to understand diodes well enough to put LEDs in our circuits. I can't tell you how much of a relief it is to finally find some explanations that actually answer more questions that they raise. Thank you so much for this video!

Pretty intresting.

What is charge? Somewhere, I recall someone saying charge is emergent. Of what? There has to be some way to relate without defaulting to magical fields permeating everything. These thing act as if they do but that's not the case. Effects are localized probabilistically. In what are they localized in? What is the stuff that gets made into standing waves we call particles? We have no idea as far as I can tell. We can only measure its effects. It seems impossible to measure "it" itself.

:slow clap:

That video was great, thank you!❤

So cool man ! Thanks !

Oh my God the Semiconductor class I just took as an EE undergrad makes more sense now. It was really cool seeing the Fermi function and the Shockley Equation appear here. That was nice. And you did mention that you're working on a Fermi Function video. REALLY looking forward to that. It's one of the things that kinda confused me, since a Fermi Function of an intrinsic semiconductor indicating that the probability you can find an electron at that specific energy level being 50% does not intuitively make sense to me. I hope you can also address the confusions I have in that video. Good luck!

hello I am a random layman with access to a powerful LLM that can do mistakes please check out his answers 14:47 but my beloved AI Agent said that he thinks you might have forgotten to put a 0.5 (or ½) factor and gave me a different speed of 593 km/s after asking to seek out on the internet i am getting confused by the answer which explains the lack of constant with many divergent reasons… i am confused but it does not make your video any less interesting thanks again for your amazing work i am glad… and now i am curious about what you are about to say for the next half of the video 😅😮😅😮😂

You deserve a Nobel prize for explaining this so well!! Congratulations

11:54 can someone please explain why is it like that? Why electrons "accept" certain energy?

You give a very good explanation of what you talked about but it is my opinion that you forget some thing. Semi conductor material be it Germanium or Silicon is not used clean in diodes and transistors. It is doped with a material that has either one electron or lack an electron in the outer shell. That is as far as I know what is making it semi conducting. One electron extra makes it negative material and one lacking makes it positive. I believe that both Germanium and Silicon when totally pure is more an insulator than anything else. They have no free electrons when in the molecule structure. That is at least what we learned when I studied electronics. All the rest is mostly spot on I believe.

Im confused about what you say in regards to how the Fermi dirac distribution predicts the conductivity of a material. I was under the impression that increasing the temp of a material its conductivity.

Where did you learn all this? What class teaches molecular orbital theory?

Does the energy level determine the direction of spin?

I have degrees in Materials Science and this explains semiconductors and band gaps far better than in my class specifically dedicated to Electronic Materials

Thanks, 9th garder but you made it so easy to understand. Really opened my eyes because i have been messing with electronics for while but after watching this i realised i never fully understood semiconductors. The last graphs were amazing 👏
