Background Story: Gallium Nitride (GaN) and the Blue LED A materials breakthrough that enabled an industry and more 4 LED: light emitting diode; www.energy.gov/energysaver/led - lighting https:// www.youtube.com/watch?v=AF8d72mA41M&t=1399s The blue LED revolutionized lighting and displays, and gallium nitride broadly impacted many photonics and electronics applications. LEDs use 75% less energy and last 25 times longer Energy savings by 2035 of 569 TWh (92 1,000 MW power plants) “These won’t ever replace the kitchen light.” “The research is a waste of money.” Why it was Almost Impossible to Make the Blue LED Shuji Nakamura – UCSB Professor, Nobel Laureate, Aeluma Investor © Aeluma, Inc.
