Energy-Saving LED Pioneer Seeks
Even More Efficient Devices
Shuji Nakamura, a professor of materials and of elec-
trical and computer engineering at UC Santa Barbara,
received the 2006 Millenium Technology Prize for
inventing blue, green, and white light-emitting diodes
(LEDs) and the blue laser diode. These energy-saving
light sources have revolutionized products ranging
from flashlights to advertising signs.
The prize recognizes outstanding technological achieve-
ment aimed at promoting quality of life and sustainable
development. The award selection committee described
Nakamura's work as "the `holy grail' of semiconductor
research." The award comes with a cash prize of approx-
imately $1.3 million (1 million Euros).
