Polarons in Quasi-One-Dimensional Materials

Part of the NATO ASI Series book series (NSSB, volume 264)


An electron added to a polarizable medium gains energy by distorting its surroundings; at the same time its motion is slowed down as the electron has to drag along its polarization cloud. This combined entity of an electron (or hole) and its polarization cloud is commonly refered to as a polaron. The energy gain due to the interaction with the medium is the polaron binding energy and the increased inertia is associated with an increased polaron mass.
