Energy Nanomaterials Creation Lab
Machine-translated · View original
A lab that creates new energy-saving materials from sheets and films just one atomic layer thick.
AboutAbout the lab
From surface atoms to new materials
The lab studies new materials for developing energy-saving devices.
In ultrahigh vacuum, the lab deposits other atoms onto a crystal surface to form films about one atomic layer thick, and examines their properties at the atomic level.
On surfaces and in such films, atoms have unsatisfied bonds, so properties not found in ordinary solids (bulk) may appear.
The lab focuses in particular on post-graphene materials, which are considered strong candidates for new nanomaterials.
Key terms
- Ultrahigh vacuum
- An extremely low-pressure state in which almost all gas molecules have been removed, allowing surfaces to be prepared and studied without contamination
- Post-graphene
- Sheet-like materials about one atomic layer thick, made of elements other than carbon, that follow graphene, the one-atom-thick sheet of carbon
- Quasicrystal
- A material in which atoms are arranged in an ordered way but without the repeating periodicity of ordinary crystals
- Perovskite
- A family of compounds with a specific crystal structure, being actively studied as materials for solar cells

ResearchResearch themes
To help solve energy problems, the lab studies new materials for energy-saving devices. It forms films about one atomic layer thick on the surfaces of crystals such as metals, and examines their structures and properties at the atomic level.
*Illustrative imageCreating post-graphene materials
The lab creates two-dimensional nanosheets of Group 14 elements, such as stanene, germanene, and plumbene (post-graphene materials), which are considered strong candidates for new nanomaterials, and investigates their structures and properties.
*Illustrative imageSurfaces and ultrathin films of quasicrystals
A quasicrystal is a material whose atoms are arranged following rotational symmetries that are not allowed in ordinary crystals. The lab has investigated the atomic arrangement on the surfaces of Al-based 2D quasicrystals, and has also created ultrathin films of oxide quasicrystals (hypermaterials) and elucidated their structures.
*Illustrative imagePerovskite ultrathin films
For application to solar cells, the lab has begun research on creating ultrathin perovskite films and investigating their structures.
