- The Impossible Light Gallium Nitride, Corporate Betrayal, and the Invention of Blue Light · Liszt Think
For decades, the electronics industry deemed a bright blue LED physically impossible.
- The Color That Wasn't There…l problem, a gap in the physics of light that shaped what the electronics industry could build and what consumers could buy. The first blue gallium nitride LEDs had been developed in 1971–1973, but they were feeble. They produced light so dim that it could barely be seen in a darkened room. For…
- A Chemical Company in Tokushima…education. Temperature controls drifted, batch compositions varied, and the results taught him what worked and what did not. The first blue gallium nitride LEDs were developed in 1971–1973, but they were feeble. The researchers who made them moved on to other materials. The field had concluded…
- Building the Reactor by Hand…mura stood in the laboratory at Nichia’s Tokushima plant, facing another failed crystal growth. The substrate held nothing usable—a film of gallium nitride that had cracked during cooling, its surface a web of fractures reflecting the overhead fluorescent lights. He adjusted the gas valve on th…
