Here is the final lecture in the series on the topic of the free electron model in solid state physics. Over the next few weeks I hope to produce podcast lectures for band theory, but these will take some time so look out for these in the January.

Continuing with the topic of the free electron model, in this lecture we look at how the distribution function and the Pauli exclusion principle provides a way of understanding why the electron heat capacity of metals is so small.

Here is the first lecture in the series on the topic of the free electron model. In this lecture we look at the density of states for a bulk metal and build a model based around the Fermi surface. There are three lectures in the series so make sure you subscribe to this podcast. If there's enough interest then I'll extend the series to include the nearly free electron model and the tight binding approximation.
