Rhombohedral and Turbostratic Boron Nitride Polytypes Investigated by X-ray Absorption Spectroscopy
Weine Olovsson, Martin Magnuson
The electronic structure of rhombohedral sp2 hybridized boron nitride (r-BN) is characterized by X-ray absorption near-edge structure spectroscopy. Measurements are performed at th…
Interface Bonding of Zr1-xAlxN Nanocomposites Investigated by X-ray Spectroscopies and First Principles Calculations
Martin Magnuson, Weine Olovsson, Naureen Ghafoor +2
The electronic structure, chemical bonding and interface component in ZrN-AlN nanocomposites formed by phase separation during thin film deposition of metastable Zr1-xAlxN (x=0.0,…
Vibrational Effects in X-ray Absorption Spectra of 2D Layered Materials
Weine Olovsson, Teruyasu Mizoguchi, Martin Magnuson +4
With the examples of the C -edge in graphite and the B -edge in hexagonal BN, we demonstrate the impact of vibrational coupling and lattice distortions on the X-ray absorptio…
The origin of the core-level binding energy shifts in nanoclusters
Alexey A. Tal, Weine Olovsson, Igor A. Abrikosov
We investigate the shifts of the core-level binding energies in small gold nanoclusters by using {\it ab initio} density functional theory calculations. The shift of the 4 state…
Structure and Bonding in Amorphous Cr1-xCx Nanocomposite Thin Films: X-ray Absorption Spectra and First-Principles Calculation
Weine Olovsson, Björn Alling, Martin Magnuson
The local structure and chemical bonding in two-phase amorphous CrC nanocomposite thin films are investigated by Cr -edge () X-ray absorption near-edge structu…
Band structure of hydrogenated silicene on Ag(111): Evidence for silicane
W. Wang, W. Olovsson, R. I. G. Uhrberg
In the case of graphene, hydrogenation removes the conductivity due to the bands forming the Dirac cone by opening up a band gap. This type of chemical functionalization is of utmo…
Experimental and theoretical determination of σ-bands on ("2x2") silicene grown on Ag(111)
W. Wang, W. Olovsson, R. I. G. Uhrberg
Silicene, the two-dimensional (2D) allotrope of silicon has very recently attracted a lot of attention. It has a structure that is similar to graphene and it is theoretically predi…
Strain Sensitivity in the Nitrogen 1s NEXAFS Spectra of Gallium Nitride
Andrew Ritchie, Shaylin Eger, Chelsey Wright +9
The Nitrogen 1s near edge X-ray absorption fine structure (NEXAFS) of gallium nitride (GaN) shows a strong natural linear dichroism that arises from its anisotropic wurtzite struct…
