The surface and the interface are places where the inside and the outside of a material are connected discontinuously, and because of this singularity, new quantum phases may occur there. In addition, they are easy to manipulate from the outside world and are known to often exhibit useful functions, which are important for device applications. The goals of our group are to design and create two-dimensional quantum systems at surfaces and interfaces from atomic and molecular levels and to clarify their unknown material properties and functions. We will achieve them based on our own state-of-the-art UHV technique and nanotechnology. The current research topics include atomic-layer superconductors grown on clean silicon surfaces, bismuth atomic-layer materials, and electron conduction through diamond surfaces. We are also working on creation of new two-dimensional superconductors using the spin-orbit interaction and organic molecules.
