Bridging classical and quantum interpretation of chemical state analysis by XPS/HAXPES to resolve short-range order in amorphous alumina films
Simon Gramatte, Xing Wang, Michael Alejandro Hernández Bertrán +8
Probing the local structure and chemistry of wide-bandgap amorphous oxide thin films remains challenging due to the limitations of lab-based spectroscopy. This work integrates X-ra…
Uncovering the origin of interface stress enhancement and compressive-to-tensile stress transition in immiscible nanomultilayers
Yang Hu, Giacomo Lorenzin, Jeyun Yeom +6
The intrinsic stress in nanomultilayers (NMLs) is typically dominated by interface stress, which is particularly high in immiscible Cu/W NMLs. Here, atomistic simulations with a ch…
Atomistic simulations of the crystalline-to-amorphous transformation of gamma-Al2O3 nanoparticles: delicate interplay between lattice distortions, stresses, and space charges
Simon Gramatte, Lars P. H. Jeurgens, Olivier Politano +4
The size-dependent phase stability of gamma-Al2O3 was studied by large-scale molecular dynamics simulations over a wide temperature range from 300 to 900 K. For the gamma-Al2O3 cry…
Advanced chemical state studies of oxide films by lab-based HAXPES combining soft and hard X-ray sources
S. Siol, J. Mann, J. Newman +5
The greater information depth provided in Hard X-ray Photoelectron Spectroscopy (HAXPES) enables non-destructive analyses of the chemistry and electronic structure of buried interf…
A combinatorial guide to phase formation and surface passivation of tungsten titanium oxide prepared by thermal oxidation
Sebastian Siol, Noémie Ott, Michael Stiefel +4
TiO and WO are two of the most important earth-abundant electronic materials with applications in countless industries. Recently alloys of WO and TiO have been inve…
