Solid State Physics — Course Material

A single home for the full lecture notes, past exams, the formula sheet, course announcements, and a big-picture orientation to how the models fit together.

📓 Lecture notes

The complete Open Solid State Notes — all 15 lectures with worked solutions, interactive figures, and code. The whole course is really one recipe (states → density of states → fill with statistics → integrate) run in four acts:

ACT I

Heat from vibrations

Einstein → Debye · phonons

ACT II

The electron gas

Drude → Sommerfeld · Fermi sea

ACT III

Bands

LCAO · tight-binding · nearly-free · crystals

ACT IV

Devices

semiconductors · doping · diodes

🧭 Orientation & study companion

The narrative spine of the course — what we're actually trying to do, the one recipe behind every model, and from-scratch derivations of the Boltzmann factor and the Bose–Einstein distribution.
