The Effect of Nitrogen Doping on GaAs1−xPx Electroluminescent Diodes

Abstract
The efficiency of GaAs1−x P x diodes for x>0.45 has been found to be greatly enhanced by the addition of nitrogen doping. The diodes were fabricated by means of Zndiffusion into vapor‐grown GaAs1−x P x doped with N and Te. The effects of nitrogen doping on diode efficiency, emission spectra, and brightness as a function of alloy composition are discussed.
