Shuji Nakamura

Shuji Nakamura is a Nobel Prize-winning physicist and Professor of Materials and Electrical & Computer Engineering at the University of California, Santa Barbara (UCSB). Internationally recognised for pioneering the development of efficient blue light-emitting diodes (LEDs), his groundbreaking research laid the foundation for modern solid-state lighting and transformed energy-efficient illumination, displays, and optical storage technologies.

Beginning his pioneering research on Group III nitride semiconductors in 1989, Nakamura achieved a series of landmark breakthroughs that revolutionised optoelectronics. In 1990, he invented the Two-Flow Metal-Organic Chemical Vapor Deposition (MOCVD) system, enabling the growth of high-quality gallium nitride (GaN) crystals. He subsequently became the first to produce p-type GaN through thermal annealing and identified hydrogen passivation as the mechanism preventing p-type conductivity—a discovery that solved a challenge that had hindered GaN research for decades. In 1992, he demonstrated the first high-quality indium gallium nitride (InGaN) single-crystal layers, which became the active material for virtually all modern blue, green, and white LEDs, as well as violet, blue, and green semiconductor laser diodes. He later developed the world’s first high-brightness Group III nitride blue and green LEDs and the first Group III nitride violet laser diodes, paving the way for today’s LED lighting and Blu-ray technologies.

Nakamura was awarded the 2014 Nobel Prize in Physics for the invention of efficient blue LEDs, which enabled bright, energy-efficient white light sources. His many honors include the Millennium Technology Prize, Benjamin Franklin Medal, Charles Stark Draper Prize for Engineering, Queen Elizabeth Prize for Engineering, and Japan’s Order of Culture. He is also a member of the US National Academy of Engineering, the National Academy of Inventors, and the National Inventors Hall of Fame.

Since joining The University of California, Santa Barbara in 2000, Nakamura has served as Research Director of the Solid State Lighting & Energy Electronics Center and holds the Cree Chair in Solid State Lighting & Displays. He is the inventor or co-inventor of more than 200 U.S. patents and over 175 Japanese patents and has authored more than 550 scientific publications. He also co-founded Soraa in 2008 and SLD Laser in 2013, translating his pioneering research into commercially transformative lighting and laser technologies.
