Small Polarons: Transport Phenomena
The theory of small polarons is a huge subfield of solid state physics. It is currently enjoying a new burst of activity, particularly in Europe. Not the least of the reasons is research on Tc superconductors, fullerenes, correlated nanowires and nanotubes, quantum dots and other advanced materials.
No claim is made that this chapter completely covers all aspects and applications of small polaron theory, nor has an effort been made to compile an exhaustive bibliography. The topics of this review are the principles for constructing a theory of transport phenomena in a situation in which the mobility of charge carriers in a crystal is so low that transport cannot be described by the Boltzmann equation. The effectiveness of this approach will be demonstrated for small polarons.
