How does a reverse biased diode work at the molecular level? - Part 3 | Intermediate Electronics

We've talked about the PN junction of a diode in a few videos and we're finally talking about when it is reverse biased! In this final chapter, we talk about what's happening on the molecular level that makes it so that current doesn't flow backwards in a diode and also what happens when the voltage is so great that there's an avalanche breakdown and actually does flow!
