A01Material Creation for 2.5D Structures
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.
A02Construction of 2.5D Integrated Structures
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.
A03Development of Analysis Techniques for 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.
A04Exploration of Novel Physical Properties of 2.5D Structures
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.
A05Development of 2.5D Structures for Electronic, Photonic and Energy Applications
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.
