| Outline of Final Research Achievements |
In this work, we elucidated the deposition mechanism of organic films produced by atomizing crystallization using supercritical carbon dioxide and developed the thin film design technique of organic thin films by the present technique based on the experimental results in order to propose organic thin films deposition technique that enables to realize high-performance organic semiconductor devices by the present technique. Specifically, we systematically investigated the effects of various operating factors on the characteristics of organic thin films, accumulated basic knowledge that led to the elucidation of organic film deposition mechanisms, and clarified the thin film design guidelines. Furthermore, we measured the solubility of organic semiconductor materials in supercritical carbon dioxide, which is indispensable as a basic knowledge for elucidating the thin film deposition mechanism and proposing thin film design technique, and developed solubility estimation models.
