The lab investigates the behavior of electrons on solid surfaces through both measurement and calculation.
AboutAbout the lab
Exploring electrons in the special space of a surface
Shuto Lab studies phenomena that occur on solid surfaces through both experiments and theoretical calculations.
A solid surface is a special two-dimensional space where molecules and atoms interact with the solid, and it requires a different treatment from the interior of the solid.
Taking advantage of this environment, the lab aims to clarify the formation and control of nanoscale structures, as well as changes in electronic states upon excitation and the dynamic processes involved.
The lab also works on phenomena that form the foundation of next-generation devices and on the development of new materials.
Key terms
- Photoelectron spectroscopy
- A measurement method that shines light on a material to examine the state of its electrons. In this lab, it is used to measure electronic states at surfaces
- Scanning tunneling microscope
- A microscope that examines the arrangement and electronic states of atoms and molecules on a surface. Abbreviated as STM
- First-principles calculation
- A calculation that determines the electronic states of a material based on the fundamental laws of quantum mechanics
ResearchResearch themes
On a solid surface, a special two-dimensional environment, the lab investigates the formation and control of nanoscale structures, reactions and electronic states, and changes in electronic states upon excitation. Using both experiments and theoretical calculations, it works on phenomena that form the foundation of next-generation devices and on the development of new materials.
*Illustrative imageMeasurement and Control of Electronic States
The lab measures electronic states that appear locally on surfaces, as well as the electronic states of functional molecules adsorbed on surfaces, using photoelectron spectroscopy and scanning tunneling spectroscopy. It also performs ultrafast measurements on timescales from nanoseconds to femtoseconds using laser light.
*Illustrative imageMicroscopy
Using scanning tunneling microscopy and photoemission electron microscopy, the lab measures structures and electronic states from the atomic scale to the micron scale and reveals the arrangement of atoms and molecules. Another feature is the use of a laser as the excitation source to distinguish spin states.
*Illustrative imageElectronic State Calculations
Using first-principles calculations, the lab predicts electrons specific to impurities and surfaces, molecular arrangements and nanostructures, and magnetization, and uses these predictions to interpret experimental results. It also runs simulations that follow changes in electronic states when biomolecules bind to receptors, as well as dynamic processes such as surface reactions.
