Haven't even finished the video yet, but this has been massively helpful! I'm in a survey course about special relativity, Qmech, solids, and nuclear physics and my professor has skipped over a lot of the finer details of each of these concepts (we jumped from the electron sea to transistors/semiconductor doping in one lecture -- it's kinda rough). Band theory was one of those things that was almost entirely skipped over, but this video has cleared up a lot for me, thanks!

Oh wow, that’s so nice to hear! I’m glad it was helpful - this class you’re taking sounds epic! It’s tough to cover everything in a survey course but it sounds like you’re learning a ton!
At 9:40 you said 'insulators' but you meant to say 'semi-conductors'. Great channel. Your teaching style brilliant.

Oh dang, you're absolutely right! Thanks for catching that and your kind words!
Similar to the other commenter thus far, really cool video! Pretty broad survey course that touched on this. My prof just had us study the math of this so I've never even seen this kind of phase diagram. He isn't even a pure math physicist so I'm kinda surprised honestly, but stuff like this is outside his wheelhouse cuz he kinda hates chemistry. Typical astrophysicist 😂 Super cool to see another lecturer explain what I was experiencing in the thermoelectric materials lab, and making me super excited to take pchem!
Or would this crop up in inorganic? The survey course I studied this in was the third semester of calc-based physics, covering modern physics other than all the stuff we covered in phys2

Band theory and solid state materials are really at the intersection of so many burgeoning fields. As a chemist, I always take a molecular orbital approach but a Materials Scientist or Physicist would likely take a different approach. Even something simple like conductivity -- chemists use the flow of electrons, whereas a physicist typically uses the flow of holes or positive charges. The outcome is the same but the approach is completely opposite. We teach this in our Inorganic Chemistry course.

@@rojaslab Cool to know! I've always seen it approached from the phys and materials side, this is exactly what we were researching in the thermoelectrics lab. So cool to see it from a different angle!
