Kurzbeschreibung
Electrical Characterization of Organic Electronic Materials and Devices gives new insights into the electronic properties and measurement techniques for low-mobility electronic devices; characterizes the thin-film transistor using its own model; links the phenomena seen in different device structures and different measurement techniques; presents clearly both how to perform electrical measurements of organic and low-mobility materials and how to extract important information from these measurements; and provides a much-needed theoretical foundation for organic electronic.
