Quantum Well Design for Red-Emitting InGaN LEDs
TS-042441 — The quantum well design is incorporated within a red-emitting InGaN QW LED, an LED type that usually cannot efficiently emit wavelengths larger than blue/green. The LED can be incorporated into a same-material RGB platform for white LEDs, because the well design increases efficiency and decreases indium composition compared to similar wavelength InGaN LEDs.
Blue-emitting InGaN quantum well (QW) LEDs now have 69% external quantum efficiency, but increasing the emitted-wavelength decreases the efficiency significantly. The inversion asymmetry of the InGaN lattice increases the induced strain, which in turn increases the piezoelectric effect. Charge bui…
