We have investigated the effects of white-light illumination on the electrical performance of organic polymer thin-film transistors (OP-TFTs). The OFF-state drain current is significantly increased, while the drain current in the strong accumulation regime is relatively unaffected. At the same time, the threshold voltage is decreased and the subthreshold slope is increased, while the field-effe...

THE deposition of organic semiconductors, e.g. Pentacene (C22H12) and Alq31, becomes more and more important. Due to lower process temperatures, the manufacturing of organic electronic devices such as light emitting diodes (OLEDs) and thin film transistors (OTFTs) is less energy consuming. Additionally, these low temperatures also make it possible to use flexible substrates, e.g. plastic films,...

a r t i c l e i n f o Thin-films and organic field-effect transistors fabricated from a solution-processable precursor of zinc tetra-benzoporphyrin (ZnTBP) are reported. Amorphous, insulating precursor films were deposited by spin-casting and thermally converted into polycrystalline, semiconducting thin-films comprising grains on the order of 5 μm in diameter. Thin-film X-ray diffraction indica...

Organic field-effect transistors using small-molecule organic single crystals are developed to investigate fundamental aspects of organic thin-film transistors that have been widely studied for possible future markets for 'plastic electronics'. In reviewing the physics and chemistry of single-crystal organic field-effect transistors (SC-OFETs), the nature of intrinsic charge dynamics is elucida...

Electrical characteristic of amorphous indium gallium zinc oxide (a-IGZO) thin film transistors (TFTs) on flexible substrate are investigated with various channel width and length. Its electrical properties according to the physical dimension of the channel are analyzed through Technology Computer-Aided Design (TCAD) simulation. Index Terms — Density of states (DOS), flexible, In-GaZn-O (IGZO),...
