Schottky Diode Part 2 - Depletion Region and Capacitance

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. 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.
