Positive mind in your tough time brings opportunity.
Considering a bit more deeply always helps.

It is by accident ten years ago that I joined the research field of organic semiconductor materials, which seizes my heart and mind now. When I was dreaming of applying the technology of field-effect transistors various exotic materials to control electron density simply by external electric field, many fascinating data appeared in journals reporting such effects using organic materials, which turned out to be a fake afterwards. Since I already invested a lot before I recognized the truth, the incident caused the greatest pinch in my life. However, it was because of this unusual experience that I deeply noticed very different characters of organic materials, i.e. softness, low electronic charge density, and controllability by external stimulation as a result. The experience also taught me the power of being positive so that any uncommon experience turns into a treasure at the end. I am leading a group with experts in chemistry, physics and engineering to develop unprecedented materials with fast operating frequency for future low-cost and printable electronics industry. Your exciting ideas are welcome to contribute the future.

Introduction of the study

Introduction of the study

In the development of next-generation electronic devices, it is needed to consider their compatibility to the environment and demands for their diverse functions because of the rapid structural change in human society. Recently, organic semiconductor devices are attracting much attention as a practical candidate to meet such requirements because of their simple and low-cost production processes, low environmental burden, as well as for their unique function of flexibility. The scope of our research group ranges from basic scientific studies on materials chemistry and charge transport physics in organic semiconductor interfaces to the device functionalization and engineering of organic semiconductors.

Junshi Soeda

We enjoy our daily research progress with Professor Takeya, who is eager to think together with us, once we correctly tell him problems concerning our experimental techniques as well as interpretation of the resultant data.

The subject of organic electronics is attractive for me because our fundamental scientific finding is closely related and can give essential contribution to the real practical technology in the expected application to flexible and printed electronics in near future. I feel that the strength of our group is the mixture of people from very different backgrounds ranging from synthetic chemistry, condensed matter physics, and device engineering, so that we enjoy discussion from totally wide-ranged aspects.
