Conductivity and Semiconductors

Why do some substances conduct electricity, while others do not? And what is a semiconductor? If we aim to learn about engineering and technology, this will be a very important concept, so let's go through the basics now!

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

LOL you have carried me through 5 years of high school now you are carrying me through Undergrad in Engineering. Thank you.

That relieving feeling when you search for a topic and see Professor Dave’s head in the results.

[shubhamnath]

He know a lot about beards and stuff...
Professor Shave explains🤣

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

[souvikghoshece]

Nice video sir. This video is awesome. Please upload more videos on electronics and also on communication systems also.

[yashrajdevrat]

I'm learning electronics in my clg this is too much informative .
Where are your lengthy hair?

[IsabellaJasminy-ighf]

Insane explanation Dave, I am already a big fan of your videos. Clear and very understandable way to teach.

[manueljenkin]

This is such a well made video! Grateful for such knowledge presented in an clear and concise way.

Professor Dave.
Thanks so much for uploading this video.

i'm an electronics engineer student i'm pleased to see you make these types of vids.

[mr.bastolas.]

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!!

[jamesprince]

Can u make a video about Amazon forest?? Because u know the issues..

[melishabarboza]

Been confused for 5 weeks and your have solved all my problems

[joelvarela]

Thank u sir!! more about electronic pleaseee

[Nails]

I had been wondering about this. Specifically that about semiconductors. Thanks for the video.

Hi Sir,
When will you make an engineering playlist/course?

[Axetota]

I’d love to see some stuff about signal processing on an audio stream.

[expeditadjovi]

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

[noorularfeen]

Can you make video of explaining conductivity of semiconductor using Mott and Davis model.

[phhjessie]

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!!
