Webthe Er impurity and its complexes with N and Ga vacancies, substitutional C and O impurities, and H interstitials in wurtzite GaN. We find that, in the interior of the material, Er Ga is the dominant Er3+ center with a formation energy of 1.55 eV; Er Ga-V N possesses a deep donor level at 0.61 eV WebDec 1, 2001 · Since the existence of several meta-stable Er–O complexes is proposed from the model, we conclude that the variation of these Er–O complexes come from the difference of the coordination of 6 O atoms around Er impurity, which agree very well with the result of the EPR measurement.
