The optoelectronic technology of gallium nitride: the 2002 Benjamin Franklin medal in engineering presented to Shuji Nakamura

摘要

Professor Nakamura has fabricated the world's first, violet/blue laser diodes and world's brightest blue and green light emitting diodes. His remarkable contributions encompassed materials growth, characterization, and device development and processing. His gallium-nitride-based violet lasers improve by a factor of about three the packing density/resolution of optoelectronic storage media such as video or data storage and of printers or VCRs. His gallium nitride bright, green and blue, light emitting diodes, 10-100 times more efficient than their predecessors, enable color displays and lighting applications and are potential seeds of a new lighting industry. Professor Nakamura has opened the door to a gallium-nitride-based semiconductor industry.
