LED, from red to rainbow

IEEE Spectrum: Today LEDs come in yellow, orange, green, turquoise, blue-violet, and even white. But first there was red... They shine from clocks and traffic lights; they blink on our car dashboards. They flash on the soles of children's running shoes; they glow from the coffeemakers in our kitchens. They tell us that our modems are connecting to our networks; they reassure us that our cellphones are on. They lit up the face of the first personal computer and the first wristwatch with an electronic display; they illuminate today's suspension bridges and video billboards. These tiny semiconductor sandwiches known as light-emitting diodes (LEDs) can now create every color of the rainbow and more. But LEDs all trace their genealogies back to the first visible laser diode—and it was red. The father of that primordial visible diode is Nick Holonyak Jr., the winner of this year's IEEE Medal of Honor.

Microchip: An Idea, Its Genesis, and the Revolution It Created

Microchip brings to life the history of the integrated circuit, including a time when the very concept generated professional hostility among many electrical engineers. ... EEs at the time had built careers around selecting, qualifying, and combining individual transistors, resistors, and capacitors into purpose-built circuits. Now they were being asked to use preconfigured circuits that permitted no testing of their individual components, and many felt their livliehoods were threatened. As Zygmont clearly describes complex concepts, the problems, both technical and cultural, faced by the early microchip manufacturers and how they solved them leave the reader in awe. Although the occasional error is introduced by Zygmont's reliance on firsthand accounts, vivid eyewitness descriptions of the early days make up for them. Corporate cultures, personalities, skills at patent writing, and royalty negotiations, along with market timing and high-profile military and aerospace projects, are all part of the tale of how these strange little devices got made and eventually affected our lives. Although the historian may wish for more detail, this is a good and readable survey of a vital industry. [IEEE Spectrum, June 2003]
