Abstract : Organic thin-film transistors (OTFTs) are the enablers of all organic circuitry but are severely limited by the paucity of high carrier mobility semiconductors (especially for electron transport), poor quality of compatible insulators, high power consumption, poor understanding of how critical material interfaces affect carrier injection and transport, limited understanding of charge carrier dynamics and trapping mechanisms, and poor understanding of circuit radiation hardness. In addition, current strategies fo OTFT integration and efficient printing, essential for organic complementary circuits, are an early stage of development. The objective of this program is to develop the understanding necessary to achieve high-performance polymeric and molecular materials enabling high speed electronic circuits. This report summarizes progress towards these goals describes what we have learned in terms of fundamental materials-property-device responses, unique molecular/polymeric materials sets, and process/device platforms to advance the field of organic electronics.
