A new luminescence line due to nitrogen implanted into AlxGa1−xAs (x=0.37)

Abstract
Optical behavior of isoelectronic impurities in AlxGa1−xAs (x=0.37) is investigated. Photoluminescence of the samples implanted with N was measured at 2 °K. A new luminescence line is observed at an energy which is 90 meV below the edge emission peak. The integrated intensity of the N‐implanted sample is about five times larger than that of an unimplanted and annealed sample. This is thought to be due to the bound states produced by the N atoms which replace the As atoms.
