Frontier Technology for Energy and Devices

Effective energy use, the development of alternative energies and the development of materials and devices with new functions all play important roles in stabilizing energy infrastructure and solving environmental issues. In this field, diverse research is conducted on themes such as electrical energy generation from large-scale power sources, including thermal power generation, nuclear power generation and dispersed power systems. We study their conversion for use with machines, heat, optical energy, electric transport and other technologies using electric power, as well as for electronic physicality and devices such as super-conductors, semiconductor integrated circuit technology and nano-structure devices and materials.
