Kohei Yamasue, Associate Professor
0 student voices
The Dielectric Nanodevices Lab conducts research on dielectric measurement of electronic materials. It aims to advance measurement research that makes full use of nanotechnology and to apply the results to the development of high-performance next-generation electronic devices. Through its research activities, the lab also aims to train young researchers and students who will lead the next generation. The lab is located within the Research Institute of Electrical Communication.

Masafumi Shirai, Professor

The Physical Properties and Functional Design Lab theoretically studies quantum physical phenomena in materials used in information devices, such as semiconductors and magnetic materials, and designs new functions for them. The lab also aims to establish new methods for designing the properties and functions of materials using large-scale simulation techniques. In Professor Shirai's area, the lab carries out theoretical analysis of materials and devices for spintronics; in Associate Professor Abe's area, it studies the properties of matter that appear in high-density regimes. The lab belongs to the Computing Systems Research Division of the Research Institute of Electrical Communication.

Shunsuke Fukami, Professor

The lab studies spintronics, which makes simultaneous use of the electron's charge (its electrical property) and spin (its magnetic property). It aims to clarify the new physical phenomena that arise this way, and to contribute to high-performance, low-power electronics and information processing and communication. Research proceeds mainly in five areas, which are closely interrelated. The Fukami Lab works jointly with the Ikeda Lab and the Åkerman Lab.

Shigeo Sato, Professor

The lab studies the fundamental hardware technologies for non-von Neumann computing, centered on brain-inspired computing. By integrating a wide range of fields, including devices, processes, and circuits as well as algorithms and neuroscience, it takes on the challenge of creating entirely new computing technologies. Professor Sato's area covers brain-inspired devices and dedicated LSIs, and Associate Professor Sakuraba's area covers technologies for fabricating semiconductor quantum heterostructures.

Nobuyuki Matsuda, Professor

The lab studies how to build quantum information processing devices and systems using photonic integrated circuits. Current information processing and communication map signals onto classical, macroscopic quantities such as voltage and frequency, and it has been pointed out that this approach is approaching its limits in information density and speed. In contrast, there are strong expectations for the practical use of quantum information and communication technologies, which encode information in microscopic quantities such as individual electrons and photons and directly use the principles of quantum mechanics. The lab works on developing technologies that will be at the core of quantum information and communication in the near future.

Tomohiro Otsuka, Associate Professor

The Quantum Device (Otsuka) Lab studies the fundamental physics of nanostructures and quantum effects, and their application to semiconductor quantum technologies. This research is interesting as fundamental physics that explores how nature works, and it also leads to new technologies such as quantum computing, quantum electronics, and spintronics. After joining the lab, students take part in cutting-edge research while acquiring basic knowledge and skills. Once they are accustomed to the work, they gain experience carrying out everything on their own, from planning to publishing results. The lab welcomes new members regardless of their previous background, and lab visits are also welcome.

Ayumi Hirano, Professor

The Nano-Bio Integrated Molecular Device Lab aims to develop devices that combine microfabrication technology with biomaterials and organic materials. The lab studies medical bioelectronics, which applies semiconductor microfabrication technology to medical uses such as drug screening. It also pursues organic electronics, which makes sensors based on organic materials, and bioelectronics, which builds neural circuits from living cells to understand how the brain works. These devices can be combined with information and communication systems, and the lab aims to realize them as new technologies for a healthy society.

Bengt Johan Åkerman, Professor

The Innovative Spintronics Device Lab studies how magnetization and electric current influence each other through electron spin. The lab aims to apply the findings to computers that operate on new principles, such as brain-inspired computers and Ising machines. It also works to improve the performance and functionality of spin Hall nano-oscillators, which use the spin Hall effect to make magnetization oscillate under a DC input and extract high-frequency signals. The lab collaborates closely with the Applied Spintronics Laboratory at the University of Gothenburg in Sweden.

Rihito Kuroda, Professor
0 student voices
Kuroda Lab researches image sensors and semiconductor integrated circuits, and their applications. Students can do everything themselves in the lab's facilities, from circuit design to device measurement, camera-based imaging evaluation, and device fabrication. Research is divided into two groups: the Circuits and Systems Group, which works on image sensor research, and the Devices and Processes Group, which works on identifying the causes of variability and developing new devices. Kuroda Lab was launched in the 2022 academic year.

Masakiyo Tsunoda, Professor
0 student voices
Tsunoda Lab researches new spintronics materials that use the magnetoresistance effect. Spintronics is a field that aims to develop new devices by simultaneously using two properties of electrons: charge and spin (the source of magnetism). The magnetoresistance effect is a phenomenon in which a device's electrical resistance changes with the strength and direction of a magnetic field. It underpins spintronic devices such as hard disk read heads and MRAM. The lab was newly established in 2020 and studies spin materials engineering.
