Goal: This solid-state physics class aims at providing the basics theories that allow to understand the properties of materials, and in particular their electronic and vibrational properties. Why are some solids metallic and other semiconducting ? Can we calculate their specific heat ? What is their velocity of sound ? Applications to low-dimensional systems (including graphene and nanotubes) will serve as a bridge to nanosciences.
