尼克·何伦亚克1928—2022

诺贝尔奖争议

2014年诺贝尔物理学奖授予蓝色LED的发明者（赤崎勇、天野浩、中村修二），跳过了红色、绿色LED的发明者霍洛尼亚克与西泽润一，部分评论（包括霍洛尼亚克本人）认为不公平。但诺贝尔委员会（物理学奖）委员长Per Delsing（瑞典Chalmers University of Technology教授）在《读卖新闻》专访中提出反驳，他坚称“仔细研究发明的贡献度之后，有十足信心决定这3个人获奖”。

同年12月8日，天野浩在斯德哥尔摩发表的诺贝尔奖座（Lecture）中，也有介绍霍洛尼亚克的贡献。

2015年1月，霍洛尼亚克与赤崎、中村等人共获查尔斯·斯塔克·德雷珀奖。

Nick Holonyak Jr. (November 3, 1928 – September 18, 2022) was an American electrical engineer. 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 Urbana-Champaign, where he later became John Bardeen Endowed Chair in Electrical and Computer Engineering and Physics.

Early life and education

Nick Holonyak Jr. was born on November 3, 1928, in Zeigler, Illinois, to Rusyn immigrants. The family moved to Glen Carbon, Illinois where his father worked in a coal mine. Holonyak was the first member of his family to receive any type of formal schooling. 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."

Career and research

From 1957 to 1963, Holonyak was a scientist at General Electric'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. 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.

Inventions

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).

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. The second, co-authored primarily with Milton Feng in 2005, announced the creation of a transistor laser that can operate at room temperatures.

Personal life

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.

Recognition

Awards

Many colleagues expressed their belief that Holonyak deserved the Nobel Prize for his invention of the GaAsP laser and LED. On this subject, he said: "It's ridiculous to think that somebody owes you something. We're lucky to be alive, when it comes down to it." 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.

Commemoration

1997: The Optical Society of America (now Optica) created the Nick Holonyak, Jr. Award in his honor.

2005: Inducted as a Laureate of The Lincoln Academy of Illinois and awarded the Order of Lincoln (the State's highest honor) by the Governor of Illinois in the area of Science.

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.

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.
