What can the Fermi surface tell us about a material's properties?

[QUOTE="Henryk, post: 6185769, member: 568354"] Not necessarily so, Electrical conductivity depend on the number of carriers and their scattering time. I'm not quite certain about lithium but the Fermi surface of alkali metals is as close to a sphere as you can get (true at least in the case of potassium). One thing, for a spherical Fermi surface, the volume of the surface is a cubic function of the magnitude of the Fermi vector ( ## V_{sphere} = \frac 4 3 \pi r^3 ##). In other words, the number of free electrons is a cubic function of the Fermi vector magnitude. [/QUOTE]
