Efficiency peaking in red-light-emitting gallium-phosphide diodes

Research output: Contribution to journalArticlepeer-review


Measurements of the variation of efficiency with current of gallium-phosphide diodes emitting light at 690nm have shown a consistent relationship between the peak quantum efficiency and the current at which this peak occurs. This can be related to the number of zinc-oxygen pairs in nearest-neighbour states.
