Hey all, Quick question about BZ's and it's probably a really dumb one. Solid State isn't my favorite class... What does it physically represent? Like is the area of the BZ divided by the area of a k-state (2π/L) equal to the number of charge carriers in the system? So if there was an electron fermi surface area that takes up 5% of the Brillouin Zone, does that relate to the electron density by just being 5% of the number of charge carriers from the above division? Thanks for the explanation. It will help me out in understanding this.
