Polymer thin-film transistors (PTFTs) based on poly(2-methoxy-5-(2′-ethyl-hexyloxy)-1,4-phenylene vinylene) (MEH-PPV) semiconductor are fabricated by spin-coating process and characterized. In the experiments, solution preparation, deposition and device measurements are all performed in air for large-area applications. Hysteresis effect and gate-bias stress effect are observed for the devices at room...
Polymer thin-film transistors based on poly(2-methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylene vinylene) have been fabricated by spin-coating process and characterized. The electrical characteristics of the devices stored in dry air show obvious degradation with a smaller mobility due to oxygen effect, and lower threshold voltage. The devices present good optical response in low-light condition and optically...
