摘要： We herein present the results from our study of spray-coated poly[(9,9-dioctylfluorenyl-2,7-diyl)-co-bithiophen e] (F8T2) semiconducting polymer films for organic thin film transistor (OTFT) applications. Optimized spray-coating parameters were performed for deposition of F8T2 layer on Si/SiO sub(2) substrate treated with self-assembled monolayers (SAMs) of organosilane compounds. OTFTs fabricated from general spin-coating on the same substrate were also tested to evaluate the quality of active F8T2 layer. Comparable OTFT electrical performances can be obtained for both cases even through the spray-coated devices have high surface roughness and low overall homogeneity. The spray-coated F8T2 OTFTs on the SAMs-modified substrate exhibit a maximum hole mobility of similar to 7.8 10 super(-3) cm super(2) V super(-1) s super(-1) and ON/OFF ratios of over 10 super(5). These results confirm that the spray-coating method is a powerful tool in production of reliable and reproducible OTFTs, displaying a great potential for other solution-processable organic (opto-)electronics devices. 出版者： Royal Society of Chemistry (RSC) 出版日期： 2014-01-01 出處： RSC Advances, 2014-01, Vol.4 (57), p.30145--30149 資源來源： Royal Society of Chemistry 識別號： ISSN: 2046-2069 識別號： EISSN: 2046-2069 識別號： DOI: 10.1039/c4ra03726j
