The Atom-scale Measurement Team aims to explore and understand the physical properties of substances down to the atomic scale through ultra-precise measurements. Active research includes scientific activities based on low-temperature UHV scanning tunneling microscopy, variable-temperature UHV atomic force microscopy, pump-probe picosecond laser spectroscopy, and theoretical studies using density functional theory. The team’s effort is also focused on the development of measurement technology using new principles and its improvement. In all of its endeavors, the team integrates theoretical predictions with the experimental research.
