Theoretical electron energy-loss spectroscopy and its application in materials research.

چکیده
Electron energy-loss near-edge fine structure (ELNES) of group-III nitrides is calculated using a pseudopotential plan wave method within the framework of density functional theory. Core-hole effect and supercell size influence are investigated. Based on our present and earlier work, a comprehensive understanding of theoretical ELNES application in materials research is demonstrated: interpreting experimental spectra, predicating theoretical reference spectra when reliable experimental spectra are not available, identifying ELNES-structure correlation and estimating the reliability of experimental spectra.

متن کاملVibrational and valence aloof beam EELS: A potential tool for nondestructive characterization of nanoparticle surfaces.
In many materials systems, electron beam effects may substantially alter and destroy the structure of interest during observation. This is often true for the surface structures of catalytic nanoparticles where the functionality is associated with thin surface layers which are easily destroyed. The potential application of using aloof beam electron energy-loss spectroscopy as a non-destructive n...
متن کاملDetailed theoretical study of ELNES spectra of AlN using Wien2k and Telnes programs
One crucial advantage of electron energy loss spectroscopy (EELS) lies in its high sensitivity to local changes in the electronic structure of materials [1], and the spectra can be recorded from very small regions. This allows the study of fine features (such as composition fluctuations in alloys) which can help considerably in the characterisation of ternary Inx Ga1−x N, Alx Ga1−x N and possib...

In this work, nanostructured TiO2 and Cr-doped TiO2 thin films were deposited on glass substrate through sonochemical-chemical vapor deposition (CVD) method. The resulting thin films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-visible absorption spectroscopy, and photoluminescence spectroscopy techniques. The TiO2 thin film has nanocubic morphology and ...
متن کاملElectron spectroscopy of carbon materials: Experiment and theory
We present a comparative spectroscopic study of carbon as graphite, diamond and C60 using C1s K-edge electron energy-loss spectroscopy (EELS), X-ray emission spectroscopy, and theoretical modelling. The first principles calculations of these spectra are obtained in the local density approximation using a self-consistent Gaussian basis pseudo-potential method. Calculated spectra show excellent a...
