This article summarizes mechanisms considered to explain electronic transport in organic and polymer devices, primarily light-emitting diodes. Four tables summarize models on the basis of thermal processes such as thermionic and field emission, a variety of tunneling paths, hopping, space-charge-limited models, and several field-dependent mobility models. Energy-band diagrams illustrate and compare selected models. This article catalogs the mechanisms in an effort to easily direct readers to the relevant literature for more detailed treatments.
