Organic semiconductors are of continued interest for low-cost display drivers and logic elements. Field-effect transistors (FETs) with organic semiconductor channels have been fabricated in arrays to drive electrophoretic display pixels and polymer dispersed liquid crystals (http://www.research.philips.com/pressmedia/releases/000901a.html). Complementary logic elements and shift registers containing hundreds of organic-based FETs have been produced, and high-speed organic circuits have been fabricated on polyester substrates. The source and drain electrodes of individual FETs have been patterned using microcontact printing and inkjet methods to give extraordinary aspect ratios. Inorganic and hybrid materials have been deposited as FET semiconductors using the methods of “organic electronics”. Organic FET channels have been harnessed to demonstrate ambipolar transport, chemical sensitivity, superconductivity, and electrically pumped lasers.
