Research Areas

Our missions are to develop novel technologies with a wide range of applications in nano-science and nano-technology and to support the researchers who require farbrication of nano-meter scale specimen and thier characetrization. responsible for the operation of the Nano-Science Facility and education of the users. Our research heads fundamental nano-scale phenomena realized in ultra-low temperature and we actively advance collaborative researchs in the field.

Research Subject

  1. Nano-meter scale fabrication and characterization
  2. Maintenance of all aspect of Nano-Science Joint Labratory
  3. Educating the researchers and students for fabrication and characterization
  4. Novel application nano-structure in ultra-low temperature
