Schottky Diode Part 2 - Depletion Region and Capacitance

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 find an expression for the depletion region width and the capacitance of a schottky diode. Diode capacitance is extremely useful because it can be measured and allows us to deduce the doping of a semiconductor as well as the built-in potential of the semiconductor/metal contact. This is part of my graduate series on optoelectronics / photonics, and is based primarily on Coldren's book on Lasers as well as graduate-level coursework I have taken in the EECS department at UC Berkeley. 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.
