TI Incorporation of nitrogen in Co:ZnO studied by x-ray absorption spectroscopy and x-ray linear dichroism SO PHYSICAL REVIEW B VL 87 IS 12 AR 125206 DI 10.1103/PhysRevB.87.125206 PD MAR 25 2013 PY 2013 AB N-doped CoxZn1-xO epitaxial films were grown by reactive magnetron sputtering using a range of different N-2 and O-2 concentrations. They were studied by x-ray absorption near edge spectroscopy (XANES) and x-ray linear dichroism (XLD). The incorporation of N into the ZnO host lattice could be determined via the XLD at the N K-edge in comparison with the O K-edge and respective simulations of XANES and XLD of the various dopant configurations. The addition of nitrogen predominantly leads to the formation of molecular nitrogen on O sites (split interstitial). Only for samples grown with very low O-2 partial pressure was a small fraction of the N found to substitute for O in its atomic form.
