Let’s work together to build a sustainable world with GaN

Abstract

   I would like to focus on the necessity of the research and development of wide bandgap semiconductors, particularly GaN and their alloys, which I believe should play a major role in establishing a net-zero-carbon emission and smart society in the future. The contributions of GaN and related materials to LED lighting for energy savings are huge. The applications of these materials systems are not limited to lighting. By replacing Si-based power devices with GaN-based power devices, we can expect more than a 15% reduction in total electricity consumption. GaN-based high-voltage power devices should become the key devices in establishing renewable-energy-based electricity grids because of their high-speed switching and high-voltage capability. GaN-based high-frequency and high-power transistors will provide a unique solution for realizing millimeter-wave and even THz wireless communication systems. Research on GaN-based nitrides began at Nagoya University in 1982. At that time, the laboratory was very poor and could not afford a metalorganic vapor phase epitaxy reactor. The strong commitment of one professor led to the first demonstration of GaN-based pn-junction LEDs. In this presentation, I would like to describe how GaN-based blue LEDs were born from a poor Japanese university.  

Biography

    Prof. Amano received Doctor of Engineering from Nagoya University. From 1988 to 1992, he was a research associate at Nagoya University. In 1992, he moved to Meijo University. In 2010, he moved to Nagoya University, where he was a professor of Graduate School of Engineering. On Oct. 1, 2015, he became a director of Center for Integrated Research of Future Electronics, Institute of Materials and Systems for Sustainability, Nagoya University.

 Prof. Amano shared the Nobel Prize in Physics 2014 with Prof. Isamu Akasaki and Prof. Shuji Nakamura "for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources". He is currently developing technologies for the fabrication of high-efficiency power semiconductor  devices and new energy-saving devices at Nagoya University.
