If you want to see more of these videos, or would like to say thanks for this one, the best way you can do that is by becoming a patron - see the link above :). And a huge thank you to all my existing patrons - you make these videos possible.

Why we use the fermi function f(E) and how I like to interpret it, in terms of the percentage of occupied states at a given energy. The fermi function is one of the most important functions in all of semiconductor physics, and understanding what it means and how to use it is critical to understanding all semiconductor devices.

This is part of my series on semiconductor physics (often called Electronics 1 at university). This is based on the book Semiconductor Physics and Devices by Donald Neamen, as well as the EECS 170A/174 courses taught at UC Irvine.

Hope you found this video helpful, please post in the comments below anything I can do to improve future videos, or suggestions you have for future videos.

Awesome professor. I have no words to thank you! Extremely well explained. The whole semiconductor series got me A+ grade in exams and will definitely help me in my career too. I would like to thank you from the bottom of my heart.

4:40 does quantum physics, but feels unsure about counting. The life of a scientist

I'm an undergrad chemical engineering student at Texas. Currently brushing up on all of semiconductor physics before an internship interview with a big semiconductor company. I really appreciate these videos! You present quantum mechanics in a very intuitive way, while still conveying a lot of information. You are gonna save me in this interview. Thank you so much!

OMG, I don't need other materials to understand semiconductors, if not throughly, but more than I needed than your video. Thank you so much!

Im from germany, ive watched multiple german videos, red about it but never understood anything, but this video, which is english and normally hard to understand for me, explained it all perfectly. Thank you very much.

Wow, only 3 minutes in and this video has made this so much easier to understand than after 3 weeks of reading our textbook!
Thank you so very much. 👍👍👍🎩

6:49 - Temp. should be 300K. Kelvin scale is not a 'degree' scale like C and F. By the way amazing explanation! Thanks for the video.

It is interesting to explain to students what happens at T = 0K. The way that I do it is to divide the interval into two, piecewise continuous energy intervals. Then, we note that the exponents will either be negative or positive. Then taking limits with T -> 0K, we note that f(E) tends to 1 on the left interval and to 0 on the rightmost interval. I teach solid-state and semiconductor physics at a university in South Africa and I still enjoy watching your videos for their intuitive approach.

I am becaming a mathematican, but I gave you I like, because you are able to explain that physics-stuff.

Thanks a lot for your explanation! It was very useful when learning about semiconductors in solid-state physics. I just wanted to mention that generally one writes 1000K, not 1000 'degrees' K. Keep it up with the great content!
