The lab controls interfaces and defects in semiconductors to build next-generation devices.

AboutAbout the lab
Supporting next-generation green nanoelectronics
The Advanced Device Engineering Lab (Watanabe Lab) aims to create devices with innovative functions, starting from materials design and by combining dissimilar materials and adopting new structures.
The lab covers every stage of materials, processes, and devices in a continuous line, from elucidating the fundamental physical properties of semiconductors and controlling defects to fabricating devices, analyzing operating principles, and demonstrating high performance and high reliability.
Research topics include power electronics, which is essential for realizing an energy-saving society, and next-generation quantum devices that will open the way to ultrafast computing and perfectly secure communication.
Researchers can use process equipment in a Class 1 cleanroom, measurement and analysis tools, and a high-performance supercomputer.

ResearchResearch themes
The lab covers every stage of materials, processes, and devices in a continuous line, from elucidating the fundamental physical properties of semiconductors and controlling defects to fabricating devices, analyzing operating principles, and demonstrating high performance and high reliability. It works on power electronics, which is essential for realizing an energy-saving society, and on next-generation quantum devices, using both experimental and theoretical (computational science) approaches.
*Illustrative imageInsulating film technology for power devices
The lab studies MOS power devices that use wide-bandgap semiconductors such as SiC, GaN, and Ga2O3. By controlling surface and interface reactions at the atomic level, it explores processes for forming ideal insulating films.
Semiconductor defects for quantum technology
Focusing on single-photon sources and spin-based quantum light sources that originate from defects in wide-bandgap semiconductors, the lab works to identify promising defects in SiC. By establishing methods for forming defects and achieving free control of their light-emission and spin properties, it aims to create unconventional devices.
*Illustrative imageOptoelectronic integrated devices based on Group IV semiconductors
Using germanium (Ge) and germanium-tin (GeSn), which are Group IV materials like silicon, the lab researches and develops optoelectronic integrated devices that merge electronics and photonics. Integrating optical devices with electronic devices can make information and communications faster and drastically reduce power consumption.
*Illustrative imageComputational elucidation of semiconductor defects
Using first-principles calculations on supercomputers, the lab investigates the spin and optical properties of defects in semiconductors. Focusing on defects in wide-bandgap semiconductors and at insulating film interfaces, it strives to obtain insights that directly inform the design of materials and devices.
