/ edmundsj • 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. • Quasi-Fermi levels allow us to extend the idea of the Fermi energy to non-equilibrium conditions when the original concept of a single Fermi energy breaks down. It is a fundamental and heavily-used concept in optoelectronics when you almost never operate at or near equilibrium. • 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.
