Atom diffraction in the strong-coupling regime
Carina Kanitz, Jakob Bühler, François Aguillon +6
Analytic methods based on matter-wave diffraction are a cornerstone in condensed-matter research, providing access to static and dynamic materials properties down to the atomic lev…
Origin of circular and triangular pores in electron-irradiated hexagonal boron nitride
Umair Javed, Manuel Langle, Vladimir Zobac +9
For nearly two decades, it has been known that electron irradiation of hexagonal boron nitride (hBN) in a transmission electron microscope leads to the formation of triangular pore…
Electron-beam induced methane decomposition for in-situ carbon doping of hexagonal boron nitride
Barbara Maria Mayer, Manuel Längle, Umair Javed +3
Controlling the spatial incorporation of carbon into hexagonal boron nitride (hBN) is essential for engineering optically active defects, yet existing approaches lack nanoscale pre…
Diffraction of atomic matter waves through a 2D crystal
Carina Kanitz, Jakob Bühler, VladimÃr ZobaÄ +4
Diffraction of atoms from surfaces provides detailed insights into structures, interactions, and dynamical processes. However, currently the method is limited to measurements in re…
Explicit core-hole single-particle methods for L- and M- edge X-ray absorption and electron energy-loss spectra
Esther A. B. Johnsen, Naoki Horiuchi, Toma Susi +1
Single-particle methods based on Kohn-Sham unoccupied states to describe near-edge X-ray absorption (XAS) spectra are routinely applied for the description of K-edge spectra, as th…
Self-ion implantation and structural relaxation in amorphous silicon
J. M. Gibson, Robe Elliman, T. Susi +1
Self-ion implantation amorphization is an established approach to study the structure and properties of amorphous silicon (a-Si). Fluctuation Electron Microscopy (FEM) has consiste…
