LEDs Based on Lattice-Mismatched GaInP Alloys

Current white light generation techniques rely on color mixing from red, blue, and green light. While reasonable red and blue light-emitting diodes (LEDs) are available for this scheme, there currently exists a gap in the wavelength spectral window from roughly 530 nm to 570 nm — known as the “green gap” — where realization of efficient green LEDs is proving to be very difficult.
