The Higurashi-Takeuchi Lab studies heterogeneous integration technology, which integrates dissimilar materials and dissimilar functions, and low-temperature bonding technology. In the semiconductor field, multifunctionality and the fusion of different functions are advancing alongside miniaturization, and the integration of dissimilar materials is attracting attention as a key to the continued growth of the semiconductor industry. The lab aims to contribute to creating electronic and optical devices, sensors, actuators, and energy devices that are compact, high-performance, and energy-efficient. It also aims to contribute to advancing the electronic equipment systems that will support the future IoT society.

Tatsuo Yoshinobu, Professor

Aiming to fuse semiconductor electronics with biological functions, the Yoshinobu Lab studies chemical imaging sensors that turn the distribution of ion concentrations into images. An ordinary image sensor is a sensor that "sees light," whereas a chemical imaging sensor is a sensor that "sees ions." In addition to images of pH (hydrogen ion concentration), the sensors can measure the distribution of various ions, and applications include analysis of electrochemical systems, detection of live bacteria, observation of cells, and visualization of the inside of microfluidic devices. On the lab's website, the lab is introduced under the name "Yoshinobu-Miyamoto Lab."

The Solid-State Electronics Lab uses next-generation device materials such as graphene, nitride semiconductors, and diamond to conduct integrated research from materials to devices. Electronics, long supported by silicon technology, now faces the limits of silicon's physical properties and the barriers of ultrafine fabrication technology and cost. Developing high-performance devices from materials other than silicon is therefore regarded as a major challenge for society.

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.
