Effects of gold cluster intercalation in graphene: stationary waves and modified QPI features
Cristina Bena, Marion Cranney, Poonam Kumari +2
Gold intercalation beneath epitaxial graphene on SiC produces a cluster phase with unusual standing waves and quasiparticle-interference (QPI) features concentrated near the graphe…
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
Intercalation can strongly modify the electronic dispersion of a host material, as directly revealed by angle-resolved photoemission spectroscopy (ARPES). We develop a general iter…
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…
Acceptor and donor impurity levels in hexagonal-diamond silicon
Marc Túnica, Alberto Zobelli, Michele Amato
Recent advances in the characterization of hexagonal-diamond silicon (2H-Si) have shown that this material possesses remarkably different structural, electronic, and optical proper…
