The lab creates new materials and devices using the spin of electrons.
AboutAbout the lab
New devices powered by electron spin
The Tanaka-Ohya-Nakane-Le Lab focuses its research on spintronics.
By stacking semiconductors, metals, oxides, ferromagnets, superconductors, topological materials, and more at the atomic level, the lab creates materials that do not exist in nature.
The lab investigates the physical properties of the resulting materials and builds prototype devices, aiming to provide guidance for the future of electronics.
The lab is pioneering a new field that uses not only the charge of electrons but also their spin, which is comparable to rotation about an axis.
Key terms
- Spintronics
- A field of electronics that uses not only the charge of electrons but also their spin, which is comparable to rotation about an axis
- Epitaxial growth
- A fabrication method that builds up a thin film one atomic layer at a time, aligned with the crystal arrangement of the underlying substrate
- Heterostructure
- A structure made by layering different kinds of materials, in which distinctive properties appear at the interfaces
ResearchResearch themes
With an eye toward applications in future electronic devices, optical devices, magnetic (spin) devices, and their hybrid elements, the lab conducts basic research on new electronic materials and devices. It uses epitaxial growth to create nanometer-scale ultrathin films and quantum heterostructures in which quantum mechanical effects appear, and investigates their physical properties.
