Application of the free electron gas model Video 8 of 13
4 years ago
In this video the free electron gas model of ideal metals is applied to explain the behavior of metals in electrical and magnetic field, in particular the Hall effect is examined and the Hall coefficient derived. Electrical conductivity is derived in terms of the k-space representation. The empirical Matthiessen's rule is discussed. The thermal conductivity of metals is computed. Finally the Wiedemann-Franz law is presented and the reason that it deviates from the Lorenz number is explained in terms of the scattering within the reciprocal space representation. This is video 8 of the 13 part series.
