Looking forward to your electronic materials engineering course (I am about to transition from mechatronics to nanotechnology for my master's studies and am brushing up on my knowledge with your videos) Keep it up sir! Very much appreciated
sir please keep on doing this great job, it is really helping a LOT! I could understand many of your videos and i always search videos MADE BY YOU: and it become difficult when some of the topics are still missing :( , btw thanks for these videos sir!!
Merci pour la vidéo même si je comprends pas trop l'anglais grâce au schéma effectué et le peu de cours que je connaisse m'ont permis de bien comprendre 😅😅😅. Incroyable
Sir I have doubt can we break covalent bonds in semiconductors by applying external electric field rather than giving thermal energy ? Please clarify it
We can't break covalent bonds. They are strong. Free electrons are formed and recombined again and again in a solid crystal. If your question is to make more free electrons, then it is possible to do it by giving external electricity.
Ppl talking randomly about stuff and his looks. Me seriously trying to understand something already really explained well. *💀💀💀💀💀💀* my brain is so stubborn i swr😢
3:45 That's not really true; in principle anything can conduct electricity if the voltage is sufficiently high -- it's just that, for insulators, the ratio of current to voltage is small, meaning you need a lot of voltage to get even a low current, whereas for conductors it's high so you get a large current from a small voltage. Note that voltage is just energy per unit charge, so it's really just about how much energy is needed to get the electrons to move up an energy level. The closer together the relevant energy levels are, the smaller the amount of energy and hence voltage needed. Heck, even sulfur, which is the worst conductor out of all the elements still have a nonzero conductivity, though it's very small. For sulfur, every volt will generate only 10^(-15) amps of current per meter of substance. Very tiny, but still nonzero.

LOL you have carried me through 5 years of high school now you are carrying me through Undergrad in Engineering. Thank you.
In India, we learn this is 11th standard/+1/high school second last year☠️

@@anantverma3428 gosh why do you have to be insufferable I learned this in 11th grade and still in my first year
In Bangladesh, we learned it in class of 6

That relieving feeling when you search for a topic and see Professor Dave’s head in the results.
Truee ❤
He know a lot about beards and stuff...

Hello, where can we find his course?
I'm learning electronics in my clg this is too much informative .
Where are your lengthy hair?
i'm an electronics engineer student i'm pleased to see you make these types of vids.
Nice video sir. This video is awesome. Please upload more videos on electronics and also on communication systems also.
The most awaited one!
Professor Dave.
Thanks so much for uploading this video.
Insane explanation Dave, I am already a big fan of your videos. Clear and very understandable way to teach.
Been confused for 5 weeks and your have solved all my problems
Can u make a video about Amazon forest?? Because u know the issues..
great explanation 👦👦
This is such a well made video! Grateful for such knowledge presented in an clear and concise way.
Thank you Professor Dave
Thanks

Thank u sir!! more about electronic pleaseee
Thanks a lot
I’d love to see some stuff about signal processing on an audio stream.

Why do electrons have to access the Anti Bonding molecular orbitals in order to conduct electricity?
I had been wondering about this. Specifically that about semiconductors. Thanks for the video.
It would be great if you linked the Metallic Bonds video in this lesson, that would make it easier to understand this video. Great lesson, still!!
Hi Sir,
When will you make an engineering playlist/course?
I do hope to do that one day, but I don't even have a writer yet so it will be a while.
Nice explanation. Thank you.
love this series.
tysm professor Dave!
Thanks for making my exams look less scary
Nice haircut you are so cute! Please make a series about Hardware and how this semi cunductors come to use in CPUs etc..
Very helpful. Thank you!
Mans carrying me through Uni Engineering
Can you make video of explaining conductivity of semiconductor using Mott and Davis model.
Dave, when will you start the engineering course?
It'll be a while I'm still in the earliest planning phase.
Thank you❤🎉
You surely are doing GOD'S WORK!
if insulator have more electron in its outermost orbit why it does conduct
please more on circuitry and the practice thanks
why does p-type improve conductivity
how about dielectrics?
Thank u so much sir, u help me a lot. Is there any video that explain about heterojunction?

You??? Cut your hair??? Ohmygod what happened here?? was I gone for too long???
I thought computers worked better at colder temperatures.
But you said that semiconductors work better at higher temps?
HIIIII
You look more handsome with short hair
I have a crush on you Professor Dave

WHY DID U CUT YOUR HAIR NOOOOO💔💔
:)
Can't you just give a simple example instead of orbital, but only if you think you know a lot. OK
huh
