Coherent generation of symmetry-forbidden phonons by light-induced electron-phonon interactions in magnetite
Simone Borroni, Edoardo Baldini, Vamshi M. Katukuri +12
Symmetry breaking across phase transitions often causes changes in selection rules and emergence of optical modes which can be detected via spectroscopic techniques or generated co…
Phonons in ultrathin oxide films - 2D to 3D transition in FeO on Pt(111)
N. Spiridis, M. Zając, P. Piekarz +10
The structural and magnetic properties of ultrathin FeO(111) films on Pt(111) with thicknesses from 1 to 16 monolayers (ML) were studied using the nuclear inelastic scattering (NIS…
Dynamics and stability of icosahedral Fe-Pt nanoparticles
Paweł T. Jochym, Jan Łażewski, Małgorzata Sternik +1
The structure, dynamics and stability of Fe-Pt nanoparticles have been investigated using DFT-based techniques: total energy calculations and DFT molecular dynamics. The investigat…
Effect of edge dislocations on structural and electric properties of 4H-SiC
Jan Łażewski, Paweł T. Jochym, Przemysław Piekarz +5
The paper presents a study of two full-core, edge dislocations of opposite Burgers vectors in 4H-SiC, conducted using the first-principles density functional theory methods. We hav…
Influence of isolated and clustered defects on electronic and dielectric properties of wustite
Urszula D. Wdowik, Przemyslaw Piekarz, Pawel T. Jochym +2
The influence of intrinsic Fe defects in FeO (either single cation vacancies or prototypical 4:1 vacancy clusters) on the electronic and dielectric properties is studied within the…
