Green LED break through the bottleneck effect of light, Rensselaer Polytechnic Institute achieved results

The researchers Rensselaer Polytechnic Institute invented a kind of manufacturing method can greatly improve the green LED light weight: the nano scale etching at the junction of LED sapphire substrate and gallium nitride layer, the LED green light, and light extraction, greatly improve the internal efficiency and emission quantity.

Computer monitors and televisions by red, blue and green color, red and blue LED has been the realization of high quality and cheap production targets, and green LED production technology is the industry has been seeking a breakthrough. The technology is based on the cheapest sapphire substrate to achieve, and will improve the red and blue LED light output, will promote the development of LED in the direction of high performance and low cost. The research team leader Christian WetzEL also said the difficulty of producing green LED beyond the academic and industry expectations.
