Welcome to the world of Organic Electronics!
Since 2007, this vision has guided our effort to expand the very foundation of what electronics can be.
Conventional electronics has been built on the implicit assumption of flat and rigid substrates. Yet molecular materials exhibit properties—structural flexibility, self-organization, and interface-specific functionality —that open the possibility of integrating electronic functions onto virtually any surface, including paper, textiles, and even biological surfaces. Long before the term Internet of Things (IoT) became widespread, we proposed a broader and more fundamental perspective: electronics is not limited by the substrate on which it is formed. Rollable electronic devices, energy-harvesting textiles that generate power during everyday life, and stretchable solar cells that follow any types of motion represent only a few examples. At the heart of these technologies lie fundamental questions of condensed matter physics and physical chemistry, including intermolecular interactions, interface structure, vibronic coupling, and the dynamics of charge carriers and excitons in complex molecular systems.
Our research integrates concepts from condensed matter physics, electrical engineering, surface science, polymer science, and physical chemistry to uncover how hierarchical structures and many-body interactions in organic materials give rise to emergent electronic functionality. We aim to establish a unified understanding that connects molecular-scale phenomena to macroscopic device performance, and to use this knowledge to create new device principles.
Our current topics include organic transistors, organic photovoltaics, and flexible thermoelectric devices, spanning research from fundamental physics to proof-of-concept device demonstrations. Through these efforts, we seek to redefine the range of environments in which electronics can operate.
Another important feature of our work is the development of original measurement platforms designed to access physical quantities that cannot be obtained using existing techniques. By advancing measurement science in parallel with materials and device research, we have established a globally distinctive experimental capability that enables exploration of previously inaccessible regimes.
Our research field offers an intellectually stimulating environment for students interested in discovering new physical phenomena beyond conventional frameworks, and in bridging materials, interfaces, devices, and measurement science to open new frontiers in electronics.
