Pour ces deux dernières, nous pouvons écrire NeồII et – NeồII’, où II et II” indiquent, pour les températures Tet T’, ce qu’on peut appeler l’effet PELTIER du métal. Les effets thermo-électriques On rappelle ici ce qui a été abordé au paragraphe L’effet Seebeck et l’effet Peltier sont fondamentaux pour les applications. L’exploitation des effets thermoélectriques permet de convertir de manière élégante de l’électricité pour produire du «froid» ou du «chaud» (effet Peltier) ou.
