Heterojunction Band Diagrams Explained

If you've felt like the content here has been helpful, please consider donating to UCI with a mention of this channel: https://give.uci.edu/ How to draw band diagrams for heterojunctions (when two different semiconductors meet). Heterojunctions are critical in virtually all modern optical electronics, as well as in the study of quantum mechanics, and in this video I describe how to draw their band diagrams. 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.
