Abstract

Electrical and optical properties of high performance (AlxGa1−x)yIn1−yP light emitting diodes (LEDs) are described. The current transport mechanism is dominated by surface recombination. The orange diodes exhibit a lower surface recombination current level than the corresponding yellow and green LEDs. The device performances compare favourably with the commercially available LEDs in the orange to green spectral region.
