a huge thanks to you what i have suffered to find someone who could explain me this concept of energy band and doping clearly i'm telling ya your explanation is a pedagogical masterpiece. Thank you so much
I’m not smart about Advanced Technology but I’m one of those as much interested in as, just feel so concerned about it. I hope High Tech Companies consider more throughly developing devices or functions on semiconductor to protect biometrics. That’s really important for people using electronics based on Application of Biometric Information Service such as a smartphone since that’s been a big part of human life these days. I’m 100% for sure that’s been manipulating BRAIN WAVES . Privacy nowhere
Your video is great. I want to use part of this video. It will be used at the Gwacheon National Science Museum in Korea. Of course, I write down the source. Is it possible for me to use this video?
NEW SUBSCRIBER Well Explanation LOVE FROM KERALA (INDIA) ❤🔥 Iam a Kerala Syllabus +2 student. This video is very helpful for Plus Two Physics Chapter 14 Semiconductors Electronics 🙏 Our +2 public exam starts on March 30th. Pray for it. 😥😨
Semiconductors are core to U.S. national security and economic interests, yet nine out of 10 of them are manufactured in China and other foreign countries. WHO THOUGHT THAT WAS A GOOD IDEA !?!
Conductor: a substance that conducts electricity. Insulator: a substance that does not conduct electricity. Semiconductor: a substance that has properties between an insulator and a conductor. Doping: An impurity to (a semiconductor) to produce a desired electrical characteristic. N-semiconductor: Atoms with 5 valence electrons (Phosphorus) are added to semiconductor and provides extra electron energy level. Electrons can jump into the conduction band when the energy is provided by an applied voltage. P-semiconductor: Atoms with 3 (Bohr) valence electrons are added to semiconductor and has more holes than electrons. Electrons from the valence band can be elevated to extra hole energy levels when the energy is provided by an applied voltage.
