UE Solid state, electrons and phonons

Degrees incorporating this pedagocial element :

Description

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 semi-conducting ? Can we calculate their specific heat ? hat is their velocity of sound ? Applications to low-dimensional systems (including graphene and nanobutes) will serve as a bridge to nanosciences.
