Osram explores the route to high-performance greens
Why are green LEDs so inefficient? Is it the result of poor carrier injection, high Auger loss, strong internal fields, or simply poor material quality, asks Osram's Matthias Peter.
The InGaN-based LED is the linchpin of the LED market. It forms the key ingredient in green and blue emitters, as well as providing the foundation for white LEDs employing yellow phosphors.
