What is sommerfield model?

Answer 1

Sommerfield's model is a semi quantum-mechanics, a classical free electron model. However, it differs from the Drude's model since it is incorporate in a quantum mechanics idea such that :

- Only discrete energy levels are allowed for the electron.

- Together with the Pauli Exclussion Principle and Fermi-Dirac statistic which deal with the probability of occupancy of the energy states by electron.

- The density of available states for the electron occupancy.
