Sungkyunkwan University Details Findings in Materials Science (Large-Scale Organic Single-Crystal Thin Films and Transistor Arrays via the Evaporation-Controlled Fluidic Channel Method)
By a News Reporter-Staff News Editor at Journal of Technology -- New research on Materials Science is the subject of a report. According to news originating from Suwon, South Korea, by VerticalNews correspondents, research stated, "We report a facile and versatile approach for fabricating large-area organic thin film transistor (OTFTs) arrays via a fluidic channel method. Evaporation-controlled fluidic channel-containing organic semiconductors easily produce large-area organic single-crystalline thin films in a quite uniform manner."
Our news journalists obtained a quote from the research from Sungkyunkwan University, "The unidirectional movement of the meniscus and the subsequent film growth via solvent evaporation inside the fluidic channel correspond to the simulation based on the finite element method. Utilizing this fluidic channel method, we fabricated high-performance 6,13-bis(triisopropylsilylethynyl)pentacene OTFT arrays with average and maximal mobilities of 0.71 and 2.18 cm(2) V-1 s(-1), respectively, while exhibiting current on:off ratios of >1 X 10(6)."
According to the news editors, the research concluded: "We claim that this scalable fluidic channel method offers a competitive way to fabricate high-performance and large-area organic semiconductor devices for a variety of applications."
