About awarded research
Awarded paper
Kosuke Ito：K. Ito, M. Takenaka, S. Takagi, and K. Toprasertpong, “Revealing wake-up mechanism in ultra-thin ferroelectric HZO: Domain de-pinning triggered by oxygen vacancy annihilation exhibiting optimal wake-up frequency,” 2025 Symposia on VLSI Technology and Circuits, T11-1, Kyoto, Japan, Jun. 8-12, 2025.
This work systematically investigates the wake-up effect, a key issue in thin-film ferroelectric HZO, clarifies its physical mechanism, and proposes an efficient wake-up method.
Tomohiro Akazawa：T. Akazawa, R. Tang, H. Tang, M. Okano, K. Toprasertpong, S. Takagi, and M. Takenaka, “Ultralow-energy and fast optical switch by III-V/Si hybrid MOS optical phase shifters,” 2025 IEEE International Electron Devices Meeting (IEDM), 21-5, San Francisco, CA, USA, Dec. 6-10, 2025.This work demonstrates an ultralow-power optical switch using a MOS-type optical phase shifter developed in our laboratory, providing a technology for reducing power consumption in data servers.
