Cutting-edge semiconductor electronics for the 21st century

The appearance of a new semiconductor known as gallium nitride resulted in blue light emitting diodes, white light emitting diodes and the Blu-ray Disc, completely changing our lives. If we can now extract the full potential of this semiconductor we will be able to create new optical/electronic devices that will solve important problems in the 21st century, which encompass energy, the environment, health and medical care etc. For example we can expect long-life light sources with less power consumption, solar cells of extremely high conversion efficiency, highly-efficient inverters that will support battery car technology, small and high power UV light sources for sterilization etc. Our laboratory is promoting global cutting-edge research from the fabrication of semiconductor materials through to evaluating their properties of and creating devices while obtaining support from the Ministry of Education, Culture, Sports, Science and Technology and the Ministry of Economy, Trade and Industry in order to realize semiconductor electronics that suit the 21st century.
