PN Junction Introduction

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/ In this video I introduce the P/N junction: the most fundamental device on which all of modern electronics is built. I explain what happens when you put together a piece of N and P-type material, and why the resultant depletion region is formed. 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.
