Diffusion Capacitance Derivation

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 go over my derivation for calculating the diffusion capacitance of a PN junction diode under forward bias (I have not seen this derivation elsewhere, but it gives me much less of a headache than those in Neamen and Pieret, and gets the same result). 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.
