Abstract
Organic Thin Film Transistors
In article number 2300362, Yun Ho Kim and co-workers present a uniform water-borne polyimide thin film as a gate dielectric layer in large-scale flexible organic thin film transistors (OTFTs) over 100 cm2. A bar-coating technique is used to adjust coating solution surface tension with an alcohol as a co-solvent. This approach yields low standard deviation and nearly 100% device yield in fabricating 500 OTFT devices.
有机薄膜晶体管在文章编号2300362中，Yun Ho Kim及其同事提出了一种均匀的水性聚酰亚胺薄膜作为栅极介电层，用于超过100 cm2的大型柔性有机薄膜晶体管(OTFTs)。采用棒状涂层技术，以醇为助溶剂调节涂层溶液的表面张力。在制造500个OTFT器件时，这种方法的标准偏差很低，器件成品率接近100%。
