Interactions between small-polaronic particles in solids

PDF Version Also Available for Download.

Description

When a light particle in a solid composed of relatively heavy atoms is associated with substantial displacements of the equilibrium positions of the atoms immediately surrounding it, the composite entity may be regarded as being small polaronic. Many instances of self-trapping of electronic charge carriers, excitons and light atoms such as hydrogen are known. A significant contribution to the interaction between such particles results from interference between their atomic displacement patterns. As a result oppositely charged small polarons may experience an intermediate-range repulsion, while both like-signed and neutral entities may have a tendency to cluster. These effects can be very ... continued below

Description

When a light particle in a solid composed of relatively heavy atoms is associated with substantial displacements of the equilibrium positions of the atoms immediately surrounding it, the composite entity may be regarded as being small polaronic. Many instances of self-trapping of electronic charge carriers, excitons and light atoms such as hydrogen are known. A significant contribution to the interaction between such particles results from interference between their atomic displacement patterns. As a result oppositely charged small polarons may experience an intermediate-range repulsion, while both like-signed and neutral entities may have a tendency to cluster. These effects can be very important. As examples, the recombination kinetics of electron and hole small polarons and the ordering of defect atoms are discussed.
