Why blue LEDS are difficult to make? Scientists Find Gallium Nitride Behind it

Using sophisticated computer simulations, British scientists have uncovered the mystery of why blue light-emitting diodes (LEDs) are so tricky to make. They have revealed the complex properties of their main component – gallium nitride. “While blue LEDs have now been manufactured for over a decade, there has always been a gap in our understanding of how they actually work and ...
