Mitsuru Takenaka, Professor
Semiconductors & Electronic Devices0 student voices
The Takenaka Lab studies silicon photonics, a technology for building optical circuits on a silicon substrate. It uses the same manufacturing processes as computer chips to integrate many optical components into a single chip. Its uses are expanding beyond optical communication in data centers to computation for AI and quantum information processing, LiDAR, biosensors, and more. The lab researches new devices, circuits, and the systems that use them, with the aim of building optoelectronic integrated circuits.
Toprasertpong Kasidit, Associate Professor
Semiconductors & Electronic Devices0 student voices
The Toprasertpong Lab studies next-generation semiconductor devices that will support the AI and IoT era. As semiconductor scaling approaches its limits, methods are needed to improve computing performance without relying on scaling. Based on silicon CMOS technology, the lab builds transistors that integrate oxide semiconductor and ferroelectric materials on top of silicon.
Masakazu Sugiyama, Professor
Energy & Batteries0 student voices
The Sugiyama Lab researches technologies that obtain electricity from sunlight with high efficiency and produce fuels such as hydrogen. If solar energy can be stored in chemical substances in regions with strong sunlight and transported to where it is used, sunlight will become a central energy source for society. The lab's goal is to develop highly efficient solar cells and electrochemical reaction devices for this purpose and to integrate them into a system. At the core of the technology are semiconductor nanocrystals, and the lab carries out everything from crystal growth to the evaluation of solar cell systems in an integrated way.
Ryo Ono, Professor
Medicine & Healthcare0 student voices
Ono Lab carries out both fundamental and applied research on atmospheric-pressure plasma. The lab studies the electrons, ions, and reactive species generated in plasma, as well as their reactions. Through experiments and measurements, the lab clarifies what reactions take place in plasma and what produces its effects. The lab also works on applications in medicine, such as cancer immunotherapy, and in the surface treatment of materials.
Michiaki Inomoto, Professor
Energy & Batteries0 student voices
The Ono-Inomoto-Tanabe Lab conducts research to link fusion with more economical power-generating reactors. The lab creates plasmas in large experimental devices, confines them with magnetic fields, and conducts experiments in which the plasmas are merged and heated. Aiming for a simple, low-cost fusion reactor core, the lab conducts experiments on the spherical tokamak. It also works on laboratory astrophysics, which studies the behavior of the Sun and stars in the laboratory, and carries out joint experiments with overseas research institutions.
Yasuyuki Ozeki, Professor
Imaging & Sensing0 student voices
The Ozeki Lab studies innovative optical technologies for biology and medicine. Transparent biological samples usually cannot be observed unless they are stained with dyes or labeled with fluorescence, which is laborious. The lab is developing stimulated Raman scattering microscopes that use state-of-the-art laser technology to detect molecular vibrations, allowing rapid observation without staining. Rapid observation is needed in medical settings such as surgery, where tumor boundaries must be quickly distinguished from healthy tissue.
Shinobu Ohya, Professor
Semiconductors & Electronic Devices0 student voices
Ohya Lab studies spintronics, a new kind of electronics that uses the electron's "spin." Conventional electronics has mainly used the electron's "charge." The lab uses spin inside materials such as semiconductors and oxides to explore new materials and physical phenomena, with the aim of realizing devices. Because spin is sensitive to crystal quality, the lab grows high-quality crystals controlled down to the atomic level using molecular beam epitaxy equipment.
Taro Nakajima, Associate Professor
Quantum & Condensed Matter0 student voices
The Nakajima Lab studies the properties of solids using neutron scattering. Neutrons are particles that carry no electric charge but have spin, so they can reveal both the positions of atoms and the arrangement of magnetism inside a material. Because neutrons cannot be produced in a university laboratory, the lab travels to facilities in Tokai Village, Ibaraki Prefecture, such as the JRR-3 research reactor and the J-PARC high-intensity proton accelerator facility, to carry out experiments. The lab searches for unusual magnetic orders in which neighboring spins are arranged at an angle to one another, and for the phenomena that arise from them.
Kimura Takashi, Associate Professor
Imaging & Sensing0 student voices
The Kimura Lab develops microscopic imaging technologies that use X-rays. X-rays have much shorter wavelengths than visible light and high penetrating power, so they can be used to examine fine structures and internal features that cannot be seen by eye. Using ultra-precision fabrication techniques, the lab makes optical elements for X-rays, and together with collaborators it assembles optical systems at large synchrotron radiation facilities such as SPring-8 and SACLA. The lab aims to create measurement methods that can be applied to any target, whether materials, devices, or living organisms.
Yukio Hasegawa, Professor
Quantum & Condensed Matter0 student voices
The Hasegawa Lab uses scanning tunneling microscopy and atomic force microscopy to study material surfaces at the atomic scale. A sharp needle is brought extremely close to a surface, and the tunneling current that flows is used to measure surface topography and electronic states. The lab works on two-dimensional superconductivity at surfaces, unconventional superconductivity, the magnetic structure of magnetic thin films, and measurement of spin flow. The lab also puts great effort into developing microscopes that operate in special environments, such as ultralow temperatures, strong magnetic fields, and under microwave irradiation.
