1. Details of Research Area
Materials science has established the basis of our modern society through the development of emergent internet of things(IoT) technologies. Traditional materials science is mainly based on the precise control of bulk materials with rigid chemicalbonds. On the other hand, two-dimensional (2D) materials, such as graphene, offer novel ways to make new materials by
integrating different layers via van der Waals interaction. This is accomplished by artificial stacking of 2D materials with
controlled compositions and stacking angles, an approach that is expected to significantly expand the frontier of materials
science. Furthermore, well-defined 2D nanospace existing between the layers of stacked 2D materials offer the opportunity toexplore novel phenomena and to synthesize new materials.
In this Research Area we propose to explore the"Science of 2.5 dimensional materials" by introducing
the new concepts "freedom of integration" and "2Dnanospace", in combination with the synthesis of a wide
variety of 2D materials. We will develop academic
research based on this unique “2.5D” concept to achieve
world-leading results, giving rise to upcoming socialinnovation.
This Research Area consists of five
Research Groups (A01~A05), and all the members inthis area collaborate closely to establish the newscientific field. In addition, the collaborations aresupported by the four joint research centers of the groups, allowing access to a wide range of facilities, such as automatic stacking
equipment.
2. Call for Proposals and Expectations for Publicly Offered Research, etc.
In this Research Area, we are developing unique and novel 2.5D material research by integrating the strength of the groupmembers through close collaborations. Therefore, researchers applying to this Publicly Offered Research are strongly
encouraged to describe a detailed collaboration plan with some of the group members, in addition to an original research plan(if some collaboration has already been done, please also include the achievements). It is also required to indicate how theproposed research can contribute to this Research Area.
The following are the details of the possible research topics: (1) Material synthesis and assembly: synthesis of novel 2D
materials including organic-inorganic 2D superstructures, such as COF and MOF, proposal of new assembly technology of 2D
materials, proposal of exploring the potential of 2D nanospace by introducing molecules or new architectures. (2) Analysis:
development of new methods to analyze thin 2.5D materials with high spatial/energy resolution and high sensitivity, and new
methods to detect defects and impurities of large 2.5D wafers in short measurement time. (3) Physical properties and appliedresearch: research which is not covered with the present members. Topics like strongly correlated electron systems, quantum
information, spintronics, terahertz devices, applications in information communication (6G), thermoelectric applications,
MEMS/NEMS, and tribology are welcomed. (4) Theoretical solid state physics and quantum chemistry that explain the scienceof 2.5D materials, enabling the prediction of new physical properties based on the combination of different 2D materials. In
addition to the topics listed above, we also seek for proposal on challenging topics that can dramatically advance this Research
Area. Finally, we also encourage applications from young researchers and female researchers.
