Communications, networks, and services are continually evolving, and the world of so-called ��Cloud��, in which the boundary of application fields becomes gradually fuzzy, comes true. Semiconductor devices play an important role as core components in the wide-range applications from the DNA analysis to the automatic control of the rocket, and work behind the all kinds of scenes in the social infrastructure. Adding ��nano-scaled hetero-material thin films (NHTF)�� to the semiconductor technologies, it enables to create a function-merged device, which can manipulate multiple information medias, that is, quanta called an electron, a photon, a molecule, and a spin. This novel device will start to come up a paradigm shift, that is, a scientific revolution beyond the common wisdom of the moment, in the wide fields of medical procedures, information processing, human life, and communication networks.

In our laboratory, based on the silicon technology leading the semiconductor industry, we are exploring the creation of novel NHTFs with flexible thinking, by adding germanium, carbon, Ⅱ-Ⅵ oxide semiconductor with transition metals, and by utilizing the superstructure of complex system.

Research subjects:

  1. Formation of Ge quantum dots by control of atomic sub-monolayer deposition
  2. Growth of ultra-thin relaxed heteroepitaxial films by domain matching epitaxy.
  3. Growth of transparent conductive oxide by transition metal doping.
  4. Fabrication of flexible sensors.
  5. Formation of rare-earth free ZnO-based phosphor films.
  6. Construction of multi-material platform to create the function-merged device.
