The Nobel Amano Advanced LED Research Center creates new applications through efficiency and performance that surpasses existing photovoltaic and energy devices and conducts research to develop advanced devices based on nanostructure technology of nitrate semiconductors.
To secure global research capabilities and market commercialization goals, we will create the best research environment through advanced research guidance and joint research cooperation with Professor Amano, winner of the 2014 Nobel Prize in Physics, as a leading authority and expert in this field.
GIST is committed to building a successful research environment while striving for excellent research results at the Nobel Amano Advanced LED Research Center, and we will do our best to contribute to the development of related industries and the training of outstanding human resources.
You won the 2014 Nobel Prize in Physics. What was the essence of your Nobel Prize acceptance speech in Stockholm, Sweden? Please briefly introduce the focus of your research to the public
The most important point of my speech was not related to my research but to express my gratitude and appreciation to the previous researchers of GaN, especially Professor Jack Pankove, Dr. Paul Maruska, and my supervisor Professor Isamu Akasaki, for their continuous contribution to research that led to the fabrication of blue LEDs based on GaN. Without their efforts, I could not have developed the low-temperature buffer layer technology or p-type GaN. People can now enjoy smartphones having full color displays because of the emergence of blue LEDs. In Japan, total electricity consumption can be reduced by about 7% by replacing conventional incandescent and fluorescent light bulbs with LED lighting system. Most importantly, we can provide compact lighting systems to the younger generation, especially children in remote areas without access to electricity. Using a combination of an LED light with a solar panel, children can read books and study at night.
As the director of the "Amano Center for Advanced LEDs, GIST (Gwangju Institute of Science and Technology) ," what is the ultimate direction and goal that you want the research center to pursue?
We are interested in developing any kind of LED-based device or systems that will provide major benefits to humankind. Full color micro/nano-LED displays are one example. We are facing a rapid expansion in the amount of information transmitted. Now, we are using smartphones or PCs as the interface between the internet and humans. In general, we are using our fingers to control these devices, the speed of which will not be sufficient in the future so we need a much faster interface system and method of control. We believe that micro/nano-LED displays controlled by the motion of the eye are the most promising next- generation interface between the internet and humans.
Please briefly introduce to us the key areas of joint research that you are conducting with the Amano Center for Advanced LEDs , and GIST
We are accepting one doctoral course student from GIST, and our joint research is based on his activity at Nagoya University. The aim of his research topic is to establish process technology, for active matrix LED display wafers driven by CMOS.
In 2016, there was a lecture called "Meeting Noble Laureates" at GIST. Do you have any memorable experiences or impressions of GIST students during that lecture?
Visiting GIST where I gave a talk and had a discussion with the students, was a heart-warming experience. I was very happy to receive so many excellent questions from the students. Also, I was touched by the very kind hospitality of one of the students of Professor Dong-Seon Lee, Principal Investigator of ACALEDs, who picked me up at the airport and took me to GIST. The discussion with him in the taxi to GIST was very invigorating.
Please share any final thoughts with our audience.
I am very lucky to be carried out joint research with Professor Dong-Seon Lee, one of the top researchers of GaN-based micro-LED display fabrication. Combining the device process technology being developed at GIST and the crystal growth technology being developed at Nagoya University will surely lead to new internet－human interfaces. If there are any students at GIST who are interested in our group activity, please do not hesitate to contact me. We will give you a very warm welcome if you visit us and decide to join us to carry out joint research.
