A research team at Saga University in Saga, Japan, has created a new green LED that the researchers contend is only a fraction of the cost, but can be as energy efficient, according to an article in Nikkei Net.
Instead of using the more expensive molecular beam epitaxy, the researchers used what the article called thermal diffusion. Also, instead of using gallium phosphide, one of the frequently used but pricy compounds for green LEDs, the researchers used zinc telluride.
