Machine-translated · View original
The lab builds quantum devices by stacking materials that are only one atom thick.
AboutAbout the lab
Stacking single-atom layers at will.
The Aoki Lab studies quantum devices made by semiconductor microfabrication, as well as quantum transport phenomena in graphene.
Graphene is graphite reduced to a single atomic layer, and electrons move through it with great ease.
The lab also works on other low-dimensional materials, such as transition metal dichalcogenides.
It also develops new nanoscale microfabrication and measurement techniques using scanning probe microscopy.
Key terms
- Graphene
- A sheet of carbon atoms arranged in a hexagonal pattern, only one atom thick
- Transition metal dichalcogenide
- A layered material made of a transition metal and sulfur, selenium, or tellurium. Some of them have a bandgap even at one atom thick
- Quantum point contact
- A structure in which the path of electrons is narrowed down to a nanometer-scale width. The flow of current changes in steps

ResearchResearch themes
The lab conducts basic research on elucidating quantum transport phenomena and on device applications, using quantum devices made by semiconductor microfabrication and graphene. It also works on low-dimensional materials such as transition metal dichalcogenides, and on new microfabrication and measurement techniques based on scanning probe microscopy.
*Illustrative imageVan der Waals Heterojunction Devices
Materials only one atom thick, such as graphene and h-BN, have no dangling bonds sticking out of their surfaces, so they can be freely stacked using van der Waals forces. By cutting, pasting, and stacking them, the lab aims to make devices with properties that the original materials do not have.
*Illustrative imageQuantum Devices from Graphene and TMDs
Monolayer graphene has no bandgap, but bilayer graphene opens a bandgap when an electric field is applied perpendicular to the plane. The lab sandwiches it between h-BN to raise its mobility, and is working to fabricate quantum point contacts and quantum dots.
*Illustrative imageControlling Material Properties with Laser Irradiation
Transition metal dichalcogenides are two-dimensional materials that have a bandgap even when only one atom thick. By irradiating MoTe2, which behaves as a semiconductor, with a laser in various environments, the lab succeeded in doping p-type and n-type carriers with high precision.
*Illustrative imageTMD Monolithic Devices
Within a single MoTe2 crystal, the lab created separate regions that act as p-type and n-type, and succeeded in operating the crystal as an inverter. It is now working to realize an ultra-high-performance tunnel FET using this technique.
