| 研究実績の概要 |
The homogeneously unidirectional dewetting was realized on large-area microdroplet arrays. This process allows the scaling-up deposition of thin films including organic semiconductors and transition metal oxides as the autogenous shrinkage of droplets, which further enables the fabrication of large-area organic thin-film transistor (OTFT) arrays. The resulting field-effect mobility and on/off ratio of fully-printed OTFTs exceeded 13 cm2 V-1 s-1 and 108, respectively. The presented method would not need any template and is totally compatible with conventional photolithography that has been widely used in the industry of TFT technology.
