Band Transport in Crystalline Solids

This lecture discusses band transport in crystalline solids, focusing on the criteria for band transport, examples of band transport at low temperatures, and charge transfer complexes. It covers the relationship between band width and carrier residence time, as well as the concept of band-like transport in highly ordered crystalline solids. The lecture also explores the second quantization formalism for non-relativistic quantum mechanics, emphasizing the use of annihilation and creation operators in Hamiltonians describing charge transport.
