It’s almost impossible: how I invented the blue LED [Veritasium]

It’s almost impossible: how I invented the blue LED [Veritasium] A light-emitting diode (LED) is a  semiconductor device that emits light when  current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form…
