Soluble N-Type organic thin-film transistors with enhanced electrical characteristics

We fabricated and investigated soluble, organic, thin-film transistors (OTFTs) containing ‘[6, 6]-phenyl-C61-butyric acid methyl ester (PCBM)’ as a semiconducting layer, and an organic dielectric buffer (cross-linked poly-4-vinylphenol) as a dielectric buffer-layer to improve electrical characteristics. The semiconducting layer of the devices was fabricated by the drop-casting method where PCBM was dissolved in three different solvents …
