Organic electronic materials have many applications andpotential in low-cost electronics such as electronic barcodes andin light emitting devices, due to their easily tailored properties.While the chemical aspects and characterization have been widelystudied, characterization of the electrical properties has beenneglected, and classic textbook modeling has been applied. This ismost striking in the analysis of thin-film transistors (TFTs) usingthick ?bulk? transistor (MOS-FET) descriptions. Atfirst glance the TFTs appear to behave as regular MOS-FETs.However, upon closer examination it is clear that TFTs are uniqueand merit their own model. Understanding and interpretingmeasurements of organic devices, which are often seen as black-boxmeasurements, is critical to developing better devices and this,therefore, has to be done with care.

Electrical Characterization of Organic Electronic Materialsand Devices

• Gives new insights into the electronic properties andmeasurement techniques for low-mobility electronic devices
• Characterizes the thin-film transistor using its own model
• Links the phenomena seen in different device structures anddifferent measurement techniques
• Presents clearly both how to perform electrical measurements oforganic and low-mobility materials and how to extract importantinformation from these measurements
• Provides a much-needed theoretical foundation for organicelectronics
