Sumitomo Chemical has decided to start collaborative research projects with the University of Tokyo, Tokyo Institute of Technology, and RIKEN, respectively, in April of this year, in order to undertake the research and development of strong correlation materials with the aim of developing environment-friendly devices. Research units will be established within the universities and research institute for these projects. Strong correlation materials are expected to become one of the important materials for next-generation quantum devices. While utilizing cross appointment, in which researchers will conduct research and development in multiple organizations, Sumitomo Chemical will ensure coordination among these projects, as well as strive to maximize research results and quickly implement them in society.

 

The group of materials that have a strong electron-electron interaction is called “strong correlation materials.” They have garnered attention as quantum materials that can generate innovations in the　electronics field, in particular. Since many of their electrons interact in complex ways via electric charges, spins, and orbits, strong correlation materials have potential for exhibiting such characteristics as high speed, power saving, and multiple functions, the likes of which have never been seen in conventional metal or semiconductor materials. In addition, research has shown that these materials could bring forth new physical phenomena that cannot be imagined in conventional materials systems.

 

Examples of industrial applications using strong correlation materials include next-generation memory, such as ultra-low power consumption ferroelectric memory and magnetic memory, as well as energy harvesting devices, which can efficiently convert ambient energy, such as light and heat, into electric energy. Sumitomo Chemical believes that strong correlation materials will become an essential technology in the next generation because they could contribute to both energy saving and energy generation. Accordingly, the Company will undertake the development of strong correlation materials and their production processes while conducting proof-of-concept research for environmentally-friendly devices using them.

 

To set out the research and development, Sumitomo Chemical will establish research units and cooperation programs at the University of Tokyo, Tokyo Institute of Technology, and RIKEN, which have a strong track record in basic research and applied research in this field, and conduct collaborative research targeting a broad range of themes, from search for principles and material design to proof-of-concept studies. In addition, in order to accelerate the research and development, the Company plans to send its researchers to each research unit and to ensure coordination among the projects. Furthermore, the Company will strive to quickly implement research results by leveraging its core technologies, such as function design for inorganic materials, device design, and analysis and evaluation of physical properties.
