Welcome to c/science_memes @ Mander.xyz!
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

I think you’re missing what at my university is the course: Solid State Physics, followed by a manufacturing course that may contain a lab.
This covers the physics of transistors and the basics from crystals, how to modify the properties of a crystal, and quantum effects. Then you will know how electricity affects a transistor (through field effect).
Basically if you have two wires that are open, then run a live wire near these two wires, the two wires will close. That’s a very high level overview of a field effect transistor.
