Thermoelectricity from applications to fundamental theory
Vendredi 3 octobre 2014 14:00
- Duree : 1 heure
Lieu : Amphi Chadwick, ILL 4 - 71 avenue des Martyrs - Grenoble
Orateur : Robert WHITNEY (Laboratoire de Physique et Modélisation des Milieux Condensés (LPMMC), Grenoble)
Thermoelectric effects convert heat flows directly into electricity flowsor vice versa. Materials with large thermoelectric responses (Seebeck or Peltier effects)can thus be used to build power generators and refrigerators with no moving parts. In this talk, I will review the quantum physics of thermoelectrics.
I will start by introducing the current applications of thermoelectrics,for example as the power source on the Curiosity Mars rover. I will then explain in simple terms how these thermoelectrics work, and how we might improve them using quantum theory combined with nano-engineering.I conclude by asking what insight such thermoelectric effects gives us intothe challenging field of quantum thermodynamics.
