Quantum Wells Explained

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.

Quantum wells are a fundamental and critical building block of almost all modern optoelectronic devices. From LEDs to lasers to optical modulators, quantum wells are ubiquitous. In this video I introduce the 'quantum well' and what we mean when we use the term (just a discontinuity in the conduction or valence band, in the context of semiconductors).

This is part of my new series on optoelectronic and photonic devices, a course where we explore the quantum and macroscopic nature of devices and structures that interact with light.

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.
