UNISOKU collaborated with Professor Hidemi Shigekawa and his team from the Department of Applied Physics, Faculty of Pure and Applied Sciences at the University of Tsukuba to develop a time-resolved STM system by combining the optical pump-probe method and STM.
Advanced material research in recent years has demanded measurement technologies that can visualize carrier dynamics when quantum structures are optically excited. Time-resolved STM, which has both high time resolution and spatial resolution, is the optimal measurement method, and research on semiconductor materials using this technique has been reported by the Shigekawa Lab. We have successfully developed an optical pump-probe STM that greatly simplifies the previous complicated optical systems, allowing for easy and long-term stable time-resolved STM measurements.
Based on this achievement, UNISOKU will proceed with product development and hopes that this powerful measurement technology will become widely used and contribute significantly to the advancement of cutting-edge material development in the future.
This development was supported by the Adaptable and Seamless Technology Transfer Program through Target-driven R&D (A-STEP), Japan Science and Technology Agency (JST).
