Abstract

We report on high performance organic thin-film transistors fabricated by spray-deposition, an innovative coating technique for organic electronic devices. This method is simple and inexpensive, compatible with room-temperature processing and easily scalable from laboratory-based devices to large-area electronics. Our spray-deposited 2,8-difluoro-5,11-bis (triethylsilylethynyl) anthradithiophene transistors show very good homogeneity, with mobilities of 0.2cm2/V s, and on/off ratios of 107. This performance is comparable to that of our best spin-coated devices fabricated on the same substrate type, while offering additional advantages such as using 20 times less organic semiconductor and facilitating fast coating of large-areas.
