Direct observation of defect levels in InN by soft x-ray absorption spectroscopy
Article Abstract:
Synchrotron-based near edge X-ray absorption fine structure (NEXAFS) spectroscopy was used to study the electronic of nitrogen-related defects in InN(0001). The NEXAFS revealed several defects created by ion-bombardment within the band gap or the conduction band around the nitrogen K-edge of InN and it also provided conclusive experimental evidence for the formation of interstitial nitrogen.

Structural, electronic, and optical properties of oxygen defects in [Zn.sub.3][N.sub.2]
Article Abstract:
Density functional theory is used to study the structural, electronic and optical properties of oxygen-defective [Zn.sub.3][N.sub.2]. The results have shown that [Zn.sub.3][N.sub.2] with nitrogen replaced by oxygen is more stable than that with interstitial oxygen and substitutional oxygen for nitrogen in defective [Zn.sub.3][N.sub.2] is responsible for the n-type conduction character.

Photoelectron spectroscopic investigation of nitrogen-doped titania nanoparticles
Article Abstract:
A series of titania (TiO2)-based nanometer-sized photocatalysts, including nitrogen-doped TiO2 nanoparticles (NPs), are investigated using X-ray photoelectron spectroscopy (XPS). Conclusive evidence is obtained for O-Ti-N bond formation during the process.
