Abstract

The nitrogen bonding configurations in GaNxAs1–x alloys grown by molecular beam epitaxy with 0.07<x<0.11 have been studied using x-ray photoelectron spectroscopy (XPS). In contrast to previous studies of alloys with x>=0.03, the nitrogen is found to exist in a single bonding configuration – the Ga–N bond; no interstitial nitrogen complexes are present. The amount of nitrogen in the alloys is estimated from the XPS using the N 1s photoelectron and Ga LMM Auger lines and is found to be in agreement with the composition determined by x-ray diffraction.
