Thermal diffuse scattering in TEM: complex absorptive potentials compared to the frozen phonon model

Martin Hájek, Ján Rusz

In transmission electron microscopy, electrons undergo inelastic scattering primarily through phonon excitations, known as thermal diffuse scattering. To capture the inelastic scat…

Interface-Controlled Defect Engineering in TiN/TaN Superlattices for Enhanced Hardness and Fracture Toughness

Zecui Gaoa, Qimin Wang, Julian Buchinger +6

TiNTaN superlattice coatings were designed to investigate how atomic-scale interface chemistry and defect-stabilized TaN layers govern hardness and fracture toughness. Guided by fi…

Combining Frozen Trajectory Excitation and TACAW for in silico Time-Resolved Vibrational Electron Energy Loss/Gain Spectroscopy

Wojciech Marciniak, Joanna Marciniak, José Ángel Castellanos-Reyes +1

Seeing that ultrafast (picosecond timescale) vibrational electron energy loss spectroscopy (EELS) should soon be experimentally realizable, we present in silico approach capable of…

Kagome edge states under lattice termination, spin-orbit coupling, and magnetic order

Sajid Sekh, Annica M. Black-Schaffer, Andrzej Ptok

We study the edge state properties of a two-dimensional kagome lattice using a tight-binding approach, focusing on the role of lattice termination, spin-orbit coupling, and magneti…

Optimizing spin-based terahertz emission from magnetic heterostructures

Francesco Foggetti, Francesco Cosco, Peter M. Oppeneer +4

Terahertz radiation pulses can be generated efficiently through femtosecond laser excitation of a ferromagnetic/nonmagnetic heterostructure, wherein an ultrafast laser-induced spin…
