An Interface Study Using Electron Energy-Loss Near-Edge Structure

Core-hole effects on energy-loss near-edge structure.

We present first-principles electron energy-loss near-edge structure calculations that incorporate electron-hole interactions and are in excellent agreement with experimental data obtained with X-ray absorption spectroscopy (XAS) and electron energy-loss spectroscopy (EELS). The superior energy resolution in XAS spectra and the new calculations make a compelling case that core-hole effects domi...

N-K electron energy-loss near-edge structures for TiN/VN layers: an ab initio and experimental study.

We study N-K-edge electron energy-loss near-edge structures for well-defined TiN/VN bilayers grown on a MgO(100) substrate by both calculations and experiments. The structural relaxations and the electronic structure of TiN/VN multilayers are calculated using the Vienna Ab Initio Simulation Package computer code, which uses density functional theory to describe the electronic interaction. The e...

Electron-energy-loss scattering near a single misfit dislocation at the GaAs/GaInAs interface.

Spatially resolved electron-energy-loss scattering has been used to study changes in the inelastic scattering near the bulk band-gap energy for locations near the GaAs-Ga0. 85Ino. [5As interface. %e observe the expected bulk band gap on either side of the interface. At a single interface-misfit dislocation we observe scatterIng which is consistent with an excitation of transitions between a loc...

Cubic boron nitride: Experimental and theoretical energy-loss near-edge structure

A comparison between experimental and theoretical electron energy loss near edge structure ~ELNES! of B and N K edges in cubic boron nitride is presented. The electron energy loss spectra of cubic boron nitride particles were measured using a scanning transmission electron microscope. The theoretical calculation of the ELNES was performed within the framework of density functional theory includ...
