Description: Nick Holonyak Jr., 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 (LED's) Boldly Hand Autographed Signed American Inventors First Day CoverDated 12/12/14. Excellent Condition.Includes Unsigned Reproduction Photograph 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. Holonyak predicted that his LEDs would replace the incandescent light bulb of Thomas Edison in the February 1963 issue of Readers's Digest, and as LEDs improve in quality and efficiency they are gradually replacing incandescent as the bulb of choice. In 2008, he was inducted into The National Inventor's Hall of Fame. The net proceeds are donated between two different dog rescues. Thank you for your support.
