This lecture covers the concepts of band and band-like transport in materials, focusing on the criteria for band transport, the uncertainty principle related to band width and carrier residence time, and examples of band transport in organic field-effect transistors. It also discusses charge transfer salts, complexes, and the localization of transport due to dynamic disorder coupled with lattice vibrations. Additionally, it introduces the concept of second quantization and the formalism of annihilation and creation operators, essential for describing charge transport in multi-body systems.
