A lab that discovers new quantum phenomena in materials just one atom thick.
AboutAbout the lab
Seeking new properties in materials one atom thick
The Ideue Lab studies the properties and functions of materials that are only a few atoms thick.
Layered crystals can be turned into thin films simply by peeling them off with tape, and they show properties different from those of three-dimensional crystals.
By stacking many kinds of atomic layers and applying electric fields, magnetic fields, or pressure, the lab controls the symmetry and quantum-mechanical degrees of freedom of materials.
Combining electrical and optical measurements, the lab searches for new phenomena in electrical conduction, superconductivity, and optical properties.
Key terms
- Atomic layer materials
- Thin films a few atoms thick, obtained by peeling apart crystals whose layers are held together by weak forces
- Heterostructure
- A structure made by stacking thin films of different kinds. Its properties can change greatly depending on the combination
- Raman spectroscopy
- A measurement method in which light is shone on a material and changes in the crystal's composition or structure are read from the shift in color (wavelength) of the scattered light

ResearchResearch themes
The lab fabricates devices and heterostructures of atomic layer materials and searches for new physical phenomena using electrical transport and optical measurements. By freely controlling the symmetry and quantum-mechanical degrees of freedom of materials, it explores properties that no one has yet seen.
*Illustrative imageReading Quantum States from How Electricity Flows
The lab investigates the behavior of electrons and similar particles in atomic layer materials through transport measurements. In addition to phenomena that take advantage of thinness, such as the quantum Hall effect, it uses the tunnel magnetoresistance effect to read out internal magnetic order from electrical signals.
*Illustrative imageSeeing the Symmetry of Materials with Light
The lab has its own original optical setup that allows optical measurements at low temperatures and in magnetic fields. Raman spectroscopy captures structural and magnetic phase transitions, and second harmonic generation extracts signals that depend on the symmetry of the material.
*Illustrative imageA New Measurement Approach Using Microwaves
Measuring the quantum states of extremely thin materials requires ingenuity in both the device structure and the measurement system. By combining the microfabrication technology of the Institute for Solid State Physics with tools such as microwave resonators, the lab is devising methods to measure the kinetic inductance of superconductors and spin resonance.
