First-principles calculations were performed to study the effects of inverse degree in zinc ferrite on electronic structure and properties. The electron energy-loss near-edge fine structure (ELNES) were simulated, and the splitting of peak and intensities of the oxygen K-edges can be used to identify the inversion of zinc ferrite. More Fe3+ transferring from the octahedral sites to the tetrahedral...
Defects play a crucial role in room temperature ferromagnetism of dilute magnetic semiconductors. Using valence electron energy-loss spectroscopy (EELS), it was found that the band gap of Co-doped ZnO was smaller than undoped ZnO and some midgap states appeared. Using core-loss EELS, the fine structures of the O K-edge exhibit material-specific defect features in the oxygen spectra. The EELS measurements...
