Organic single crystals of cyano-substituted p-phenylene vinylene derivatives as transistors with low surface trap density

Abstract

We obtained two high-quality lamellar crystals of cayno-substituted p-phenylene vinylene derivatives and fabricated their transistors. The transistors demonstrated hysteresis-free, low subthreshold swing values of 0.15 and 0.10 V dec−1, and high mobilities of 0.56 and 2.73 cm2 V−1 s−1, respectively. More importantly, the low defect density of 1 per 9.22 × 103 and 1.82 × 104 molecules, respectively, confirmed their high crystal quality.
