Group A01:Material Creation for 2.5D Structures (Materials Creation Group)

Creation of 2D materials based on synthesis and design technologies for high-quality 2D materials and related materials that exhibit outstanding and novel properties

We are mainly responsible for the design and synthesis of high-quality 2D materials that exhibit outstanding physical properties and unique characteristics, and create materials that will serve as building blocks for 2.5D materials science. We will conduct high-crystal and wafer-scale synthesis of 2D materials such as graphene, transition metal dichalcogenides (TMDC), and hexagonal boron nitride (h-BN), as well as research on crystal growth and fundamental science of new types of 2D materials showing exotic physical properties.

Group A02:Construction of 2.5D Integrated Structures (Integration Group)

Promoting the creation of 2.5-dimensional materials based on technologies that stack, twist, connect, and use voids in two-dimensional materials

Through the advancement and integration of individual proprietary technologies such as robotic stacking, liquid/vapor phase deposition, and intercalation, a variety of integrated structures will be fabricated.
Based on the samples provided by the Materials Creation Group, we will provide the integrated structures to the Analysis Group, the Physical Properties Group, and the Function Creation Group, and promote joint research on the control of electronic states, the search for novel quantum properties, and device applications.

Group A03:Development of Analysis Techniques for 2.5D Structures (Analysis Group)

Development and advancement of advanced analytical techniques to promote the development of unique electronic, optical, and structural properties and functions in 2.5D structures

We will develop analytical techniques to reveal the unique structures and electronic states that occur in 2.5D materials and support the academic development of 2.5D materials science.
Specifically, we will use various experimental probes (light, X-ray, electron microscopy, and electron spectroscopy) to study the electronic structure of 2.5D materials, such as the electronic state induced by moíre potentials from the angular stacking of degrees of freedom and the atomic arrangement structure in the unique 2D nanospace surrounded by 2D materials. We will advance evaluation techniques that will contribute to the promotion of research on 2.5-dimensional materials.

Group A04 : Exploration of Novel Physical Properties of 2.5D Structures (Physical Properties Group)

Understanding and developing the functionality of two-dimensional materials themselves and the electronic, optical, surface, and phonon properties induced by 2.5 dimensionality

Our goal is to design and fabricate 2.5D materials by adding stacking and nanospace degrees of freedom to 2D materials, and to develop novel physical properties. In particular, we will create 2.5D materials with unimaginable electronic, optical, and phonon properties by making full use of materials engineering, experimental techniques, and theories of physical properties. Furthermore, we will develop a new theoretical system to handle 2.5D materials, which are difficult to describe by conventional crystal physics, and provide recommendations for experiments. Through these research activities, we will be responsible for constructing an academic theory of condensed matter science, which will serve as the foundation for “2.5D materials science.

Group A05 : Development of 2.5D Structures for Electronic, Photonic and Energy Applications (Function Creation Group)

Aiming to create a wide range of functions based on electronic, photonic, and energy application technologies for two-dimensional nanomaterials and 2.5-dimensional structures

In order to realize a paradigm shift in materials science toward social transformation, we will develop an image of what are the promising applications of 2.5D materials and how 2.5D materials can contribute to society. We will develop our research with this in mind. In particular, while controlling the “interface and space,” which is the common core that constitutes devices, we will create, explore the science of, and develop applications for electronic, optical, and energy devices that utilize integrated 2.5D materials.
