Kato (Toshiaki)-Okada Lab
Machine-translated · View original
A lab aiming to create quantum devices starting from the synthesis of atomic-layer materials.
AboutAbout the lab
From nanomaterial synthesis to quantum devices
The Kato-Okada Lab develops techniques to synthesize atomic-layer materials such as carbon nanotubes and graphene with high quality and give them functions.
The lab studies the entire process consistently, from material synthesis to device design, fabrication, and functional evaluation.
The nanomaterials the lab works with are extremely small, on the scale of one-billionth of a meter, and their functions change greatly with a difference of a single atom in structure.
The lab also uses methods that combine its original nanomaterial synthesis technology with modern AI technology.
