TI Nitrogen defect levels in InN: XANES study SO RADIATION PHYSICS AND CHEMISTRY LA English DT Article; Proceedings Paper CT 20th International Conference on X-Ray and Inner-Shell Processes CY JUL 04-08, 2005 CL Univ Melbourne, Melbourne, AUSTRALIA HO Univ Melbourne DE defects; InN; XANES ID SPECTROSCOPY; NITRIDE AB The local and electronic structure of nitrogen-related defects in thin film of InN (0001) has been studied using synchrotron-based X-ray absorption near edge structure (XANES) spectroscopy. Several defect levels within the band gap and the conduction band of InN were clearly resolved in XANES spectra around the nitrogen K-edge. Theoretical analysis of XANES data includes advanced "ab initio" simulations: self-consistent full multiple scattering calculations using muffin-tin approximation, non-muffin-tin finite difference approach to study the influence of non-muffin-tin effects on XANES shape as well as advanced local density approximation scheme for optimization of initial geometry around nitrogen defects. Theoretical analysis of XANES data allows to attribute the level observed at 1.7 eV above the conduction band mimimum to antisite nitrogen and a sharp resonance at 3.2eV above the conduction band minimum to molecular nitrogen.
