Effects of gold cluster intercalation in graphene: stationary waves and modified QPI features
Cristina Bena, Marion Cranney, Poonam Kumari +2
The paper investigates how gold atoms intercalated beneath epitaxial graphene on SiC create cluster-induced scattering that generates distinctive standing-wave patterns and modifie…
An iterative method bridging DFT, disorder averaging, and experiment in intercalated materials: application to Au-intercalated graphene
Poonam Kumari, Alberto Zobelli, Igor de Melo Froldi +3
The paper presents an iterative approach that combines density functional theory, tight‑binding modeling, disorder averaging via the self‑consistent T‑matrix approximation, and ARP…
Interaction of dopants with the I-type basal stacking fault in hexagonal-diamond Si
Marc Túnica, Perpetua Wanjiru Muchiri, Alberto Zobelli +3
Recently synthesized hexagonal-diamond silicon, germanium, and silicon-germanium nanowires exhibit remarkable optical and electronic properties when compared to cubic-diamond polyt…
Direct measurement of the longitudinal exciton dispersion in hBN by resonant inelastic x-ray scattering
Alessandro Nicolaou, Kari Ruotsalainen, Laura Susana +7
We report resonant inelastic X-ray scattering (RIXS) measurements on the prototypical hexagonal boron nitride hBN layered compound. The RIXS results at the B and N K edges have bee…
Resonant X-ray spectroscopies on Chromium orbitals in CrSBr
Victor Porée, Alberto Zobelli, Amit Pawbake +4
We investigate the Cr electronic structure and excitations in CrSBr, a layered magnetic semiconductor, using a combination of resonant x-ray spectroscopic techniques. X-ray absorpt…
