ORGANIC ELECTRONICS CHEMISTRY
JUNICHI TAKEYA & YASUNARI TAMAI LAB.
INTRODUCTION OF LABORATORY
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.

MESSAGE
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.

STUDENT VOICE : CHIZURU SAWABE
In our laboratory, we are conducting the frontier research on organic electronics with our professors, who have different backgrounds from physics or chemistry. I feel that their keen ideas presented in daily discussions are always full of enthusiasm for research and are the driving force for promoting a wide range of research from basics to industrial applications. The members of our laboratory work on a wide variety of research topics, and sometimes I can get new perspectives from members whose research topics seem to have little relevance to mine.

The Goal of Applied Physics
The goal of Applied Physics is to develop a stage = “new material” that can manipulate undeveloped degrees of freedom, to explore unknown phenomena created from that stage and to bring out excellent functions, and to bring out its excellent functions. The purpose is to contribute to the development of human society by elucidating the mechanisms and developing application fields for these phenomena and functions.
