Organic field effect transistors (OFETs) are the basic building blocks for flexible integrated circuits and displays.To make OFETs, materials ranging from conductors (for electrodes), semiconductors (for active channel materials), to insulators (for gate dielectric layers) are needed. A wide range of organic molecules available in this section of the catalog are reserached as potential high-performance p- and n-type organic semiconductors. Please refer to Substrates and Electrodes section for a selection of inorganic (Au, ITO, LiF) materials and substrates commonly used in OFET and OPV research.
