Nano-photophysics
Substances having a structure smaller than the wavelength of light, and monolayer materials such as graphene exhibit unique optical and electrical properties. By creating new nanostructures and monoatomic layer materials, we will develop novel phenomena and clarify their physics. We also aim to create new devices for photonics, electronics, and spintronic using these phenomena.
Nanophotonic Materials
We pursue photonic and electronic functionalities of metal and semiconductor nanomaterials, organic molecules, and biomolecules. We also develop their hybrids, for applications to energy conversion, molecular computing, and high-density data storage, in collaboration with other groups in the center.
Nanoelectronics
We will explore a new paradigm for electronics and photonics by controlling electrons, photons, and phonons in nano/microstructures. To this end, we will establish fabrication technologies of ultrasmall electronic/photonic structures. Furthermore, electronic properties and light-matter interactions in such nano/microstructures will be investigated to realize novel information processing and photonic technologies, highsensitivity sensing, and novel electron-photon control schemes.
Nanomaterials and Nanodevices
The VLS method enables us to produce high quality semiconductor nanowires and precisely control their structures. We also try to produce novel dynamic nanostructures, whose positions and dimensions are electrically tuned, by applying surface acoustic waves to quantum well structures. Our research on spin and optical properties of these nanostructures is expected to lead to functional quantum devices.
