nobel prizeInvention of High Efficient Blue InGaN LEDs and Laser Diodes

Openning Speech by Professor Shuji NAKAMURA
Materials Department, Solid State Lighting and Energy Center, University of California Santa Barbara

The development of high brightness blue LEDs and blue laser diodes required many breakthroughs of InGaN growth, p-type conductivity control and device structures using InGaN/GaN double heterostructures. First, the speaker will discuss the history and background story of the key scientific issues solved in order to realize high efficiency solid state lighting. The fundamental discovery of high quality InGaN growth, p-type conductivity control by removing hydrogen passivation, and the role of the InGaN/GaN double heterostructure in achieving high brightness blue LEDs and laser diodes will be described.

Next the speaker will talk about the future laser lighting at the University of California at Santa Barbara. In particular, solving the current “droop” has been identified as key roadblocks to cost reduction and further improvements in solid state lighting.
