Light-Emitting Diode (LED)

A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it.

Learned from Sam Zeloof: For the discovery of a bright blue LED engineer Shuji Nakamura and physicists Hiroshi Amano and Isamu Akasaki were awarded the Nobel Prize in Physics in 2014

How do LED’s have PN junctions?

  • They’re not like Transistor, composed of a drain, a source, and a gate
