Conductivity and Semiconductors

Published 2019-08-23
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!

    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.
  • @shubhamnath8888
    He know a lot about beards and stuff... Professor Shave explains🤣

    Professor Dave. Thanks so much for uploading this video.
  • This is such a well made video! Grateful for such knowledge presented in an clear and concise way.
  • Nice video sir. This video is awesome. Please upload more videos on electronics and also on communication systems also.
  • 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!!
  • I'm learning electronics in my clg this is too much informative . Where are your lengthy hair?
  • @astrokid7664
    i'm an electronics engineer student i'm pleased to see you make these types of vids.
  • Insane explanation Dave, I am already a big fan of your videos. Clear and very understandable way to teach.
  • @Nails077
    I had been wondering about this. Specifically that about semiconductors. Thanks for the video.
  • 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

    Dave, there are many videos on measuring the band gap by varying the temperature in a 4-electrode resistivity apparatus and plotting the inverse temperature dependence vs resistivity. However, nobody seems to be a supplier of these devices. Do you know of any suppliers or any people doing research using this type of approach? Thank you!
  • Thank u so much sir, u help me a lot. Is there any video that explain about heterojunction?
