Nick Holonyak Jr. (/hʌlɒnjæk/huh-LON-yak; November 3, 1928 – September 18, 2022) was an American engineer and educator. He is noted particularly for his 1962 invention and first demonstration of a semiconductor
laser diode that emitted visible light. This device was the forerunner of the first generation of commercial
light-emitting diodes (LEDs). He was then working at a
General Electric research laboratory near
Syracuse, New York. He left General Electric in 1963 and returned to his alma mater, the
University of Illinois at Urbana-Champaign, where he later became John Bardeen Endowed Chair in Electrical and Computer Engineering and Physics.[1][2]
Early life and career
Nick Holonyak Jr. was born in
Zeigler, Illinois, on November 3, 1928.[3] His parents were
Rusyn immigrants.[2][4] His father worked in a
coal mine. Holonyak was the first member of his family to receive any type of formal schooling.[5] He once worked 30 straight hours on the
Illinois Central Railroad before realizing that a life of hard labor was not what he wanted and he would prefer to go to school instead. According to a Chicago Tribune article in 2003, "The cheap and reliable semiconductor lasers critical to DVD players, bar code readers and scores of other devices owe their existence in some small way to the demanding workload thrust upon Downstate railroad crews decades ago."[6]
Holonyak earned his bachelor's (1950), master's (1951), and doctoral (1954) degrees in electrical engineering from the University of Illinois at Urbana-Champaign. Holonyak was
John Bardeen's first doctoral student there. In 1954, Holonyak went to
Bell Telephone Laboratories, where he worked on silicon-based electronic devices. From 1955 to 1957 he served with the U.S. Army Signal Corps.[5][7]
From 1957 to 1963 he was a scientist at the General Electric Company's Advanced Semiconductor Laboratory near
Syracuse, New York. Here he invented, fabricated, and demonstrated the first visible light
laser diode on October 9, 1962. He grew crystals of the alloy GaAs0.60P0.40; a GaAs laser diode that worked in the infrared had recently been demonstrated by his General Electric colleague
Robert N. Hall. The GaAs0.60P0.40 laser diode worked at low temperatures, but the device still functioned as a light-emitting diode at room temperature.[8] The demonstration of red light emission from the diode inspired the article "Light of Hope – or Terror" in Reader's Digest. GaAsP was the material used for the first generation of commercial LEDs that came to market a few years later.[9][10][11][12]
University of Illinois
In 1963, Holonyak became a professor at the University of Illinois.[13][14] In 1993, he was named the
John Bardeen Endowed Chair Professor of Electrical and Computer Engineering and Physics at the University of Illinois at Urbana-Champaign.[15] He investigated methods for manufacturing
quantum dot lasers. He and Dr.
Milton Feng ran a transistor laser research center at the university funded by $6.5 million from the
United States Department of Defense through
DARPA.[16] Holonyak retired in 2013.[17]
In addition to introducing the III-V alloy LED, Holonyak held 41
patents. His other inventions include the red-light
semiconductor laser, usually called the
laser diode (used in
CD and
DVD players and
cell phones) and the shorted emitter p-n-p-n switch (used in light dimmers and power tools).[5]
In 2006, the
American Institute of Physics decided on the five most important papers in each of its journals since it was founded 75 years ago. Two of these five papers, in the journal Applied Physics Letters, were co-authored by Holonyak. The first one, co-authored with S. F. Bevacqua in 1962, announced the creation of the first visible-light laser diode.[8] The second, co-authored primarily with
Milton Feng in 2005, announced the creation of a
transistor laser that can operate at
room temperatures. Holonyak predicted that his LEDs would replace the
incandescent light bulb of
Thomas Edison in the February 1963 issue of Reader's Digest, and as LEDs improve in quality and efficiency they are
gradually replacing incandescents as the bulb of choice.[16]
Awards and honors
Holonyak was presented awards by
George H. W. Bush,
George W. Bush, Emperor
Akihito of Japan, and
Vladimir Putin.[5] He also received the
Global Energy International Prize, the
National Medal of Technology, the Order of
Lincoln Medallion, and the 2004
Lemelson–MIT Prize, also worth $500,000.[16] Many colleagues expressed their belief that he deserved the Nobel Prize for his invention of the GaAsP laser and LED. On this subject, Holonyak said, "It's ridiculous to think that somebody owes you something. We're lucky to be alive, when it comes down to it."[5] In October 2014, Holonyak reversed his stance by stating "I find this one insulting" in reaction to news that the inventors of the blue LED were awarded the 2014 Nobel Prize in Physics, instead of his fellow LED researchers.[18]
1973: Elected a member of the
National Academy of Engineering for contributions to development of semiconductor controlled rectifiers, light emitting diodes and diode lasers[19][20]
1989:
IEEEEdison Medal for "an outstanding career in the field of electrical engineering with contributions to major advances in the field of semiconductor materials and devices". Holonyak's former student,
Russell Dupuis from the
Georgia Institute of Technology, won this same award in 2007.[5]
June 2006: Two of Holonyak's papers were chosen by the editors of Applied Physics Letters as among the five most important published since the journal's founding in 1962.[27]
November 9, 2007:
Historical marker installed on the University of Illinois campus recognizing his development of the quantum-well laser. It is located on the Bardeen Engineering Quadrangle near where the old Electrical Engineering Research Laboratory used to stand.[28]
2015:
Charles Stark Draper Prize for Engineering "for the invention, development, and commercialization of materials and processes for light-emitting diodes (LEDs)"[30]
September 2018: Village of
Glen Carbon, Illinois, placed an honorary street sign on behalf of Holonyak, a former resident[31]
Holonyak and his wife, Katherine, were married for over 60 years. He died on September 18, 2022, in Urbana, Illinois, at the age of 93.[7]

Another important step in the development of GaAsyP1–y (or simply GaAsP) LEDs occurred in 1962 when Holonyak and Bevacqua (1962) reported on the emission of coherent visible light from GaAsP p-n junctions at low temperatures (77 K) under pulsed current injection. The emission of coherent light was limited to low temperatures. At room temperature, the devices worked as LEDs and emitted incoherent visible red light. The 1962 publication is considered a milestone in the development of pn-junction LEDs made from III–V semiconductors emitting in the visible wavelength range (Holonyak, 1987).
