有機エレクトロニクスのための材料・物性物理・プロセス開発
Development of material & fabrication process aiming at realization of organic electronics

研究の背景 Background

有機物を基盤とする電子デバイスは、柔軟性・生体適合性・大面積化などの特徴を生かすことで、これまでのシリコンエレクトロニクスでは実現困難なアプリケーションを開発できる可能性が高い。そのためには材料開発や物性測定のみならず、最終的な実装を見据えたプロセスとデバイスの開発が求められる。

Electronic devices composed of organic materials have lots of characteristics that are difficult to achieve with silicon-based electronics such as flexibility, biocompatibility, and large area processability. To make full use of such a striking feature, it's required, not only to develop materials or to investigate physical property, but also to develop fabrication processes and devices assuming what it should be.

研究の目標 Outcome

これまで、有機無機複合体や生体適合性ゲルの材料開発から、有機強誘電体および有機半導体の印刷技術に関する研究を行ってきた。有機無機複合体ではフタロシアニンダブルデッカー錯体と金ナノ粒子の複合構造の合成に成功し、20K以下で量子的な電子輸送特性を観測した。印刷技術においては表面張力や外向流によりミクロ液滴の動きをコントロールすることで高均質な有機単結晶薄膜の作製に成功した。今後は生体信号計測を始めとする柔軟なエレクトロニクスデバイスの実装技術を開発する。

I have been engaged in material development and printing technologies such as organic/inorganic composite, biocompatible gels, organic semiconductors and organic ferroelectrics. As for the organic/inorganic composite, I succeeded in synthesizing the assembled structure composed of phthalocyanine double decker complex and gold nanoparticle, and observed a quantum electron transport property below 20 K. As for the printing technology, an array of a highly homogeneous organic single crystal thin films are successfully fabricated by controlling the movement of micro droplets with surface tension and/or outward flow. In the future, I will develop a mounting technology for flexible electronic devices with the aim of detecting a biomedical signal.
