Role Of Oxide/Metal Bilayer Electrodes İn Solution Processed Organic Field Effect Transistors. Scientific Reports, 9(1), 1-8.2045-2322https://dx.doi.org/10.1038/s41598-019-43237-zhttps://hdl.handle.net/20.500.12395/38174High performance, air stable and solution-processed small molecule 2,7-dioctyl[1]benzothieno[3,2-b] benzothiophene (C-8-BTBT) based organic field-effect transistors (OFETs) with various electrode configurations were studied in detail. The contact resistance of OFET devices with Ag, Au, WO3/Ag, MoO3/Ag, WO3/Au, and MoO3/Au were compared. Reduced contact resistance and consequently improved performance were observed in OFET devices with oxide interlayers compared to the devices with bare metal electrodes. The best oxide/metal combination was determined. The possible mechanisms for enhanced electrical properties were explained by favorable morphological and electronic structure of organic/metal oxide/metal interfaces.en10.1038/s41598-019-43237-zinfo:eu-repo/semantics/openAccessArticle931040375Q1WOS:000466351100044Q1
