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 innovative approaches to create newmaterials by integrating different layers via van der Waals interaction. This is accomplished by stacking 2D materials with
controlled compositions and stacking angles, an approach that is expected to significantly expand the frontiers of materials
science. Furthermore, the well-defined 2D nanospace between the layers of stacked 2D materials provides opportunities to
explore novel physical and chemical phenomena and to synthesize new materials.
In this Research Area we propose to explore the "Science of 2.5 dimensional materials" by introducing the concepts of"freedom of integration" and "2D nanospace", in combination with the synthesis of a wide variety of 2D materials. We aim todevelop academic research based on this unique “2.5D” concept to achieve world-leading results, giving rise to upcoming futuresocial innovation.
This Research
Area consists of five Research Groups(A01~A05), and all the members in thisarea collaborate closely to establish thenew scientific field. In addition, thecollaborations are supported by thejoint research centers organized in thisArea, allowing access to a wide range offacilities, such as automatic stacking
equipment, to all the members.
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 eachmember through extensive collaboration. Therefore, researchers applying to this Publicly Offered Research are strongly
encouraged to provide a detailed plan of collaboration with some of our group members in addition to an original research plan.
Applicants also should show how their proposed research can contribute to this Research Area.
Here, “0.5D” symbolizes the new degrees of freedom offered by 2D materials including material stacking, 2D nanospacescience, and the integration of 2D materials with 0D, 1D, and 3D materials into mixed-dimensional heterostructures.
Emergence of new materials, physical properties, and applications are expected through the introduction of this “0.5D” concepts
in 2D materials research. The followings are the details of the intended candidates:(1) Researchers studying 2D material and planning to develop 2.5D research through extensive collaborations(2) Researchers who have not worked with 2D materials, but want to start 2.5D research based on their original
concepts and techniques(3) Researchers with specialized analysis techniques which are applicable to 2.5D materials(4) Researchers studying theoretical physics and materials informatics that can form the basis of 2.5D research(5) Researchers studying semiconductor devices, energy creation/storage, or areas that contribute to social innovation(6) Young researchers and female researchers
