Insights into image contrast from dislocations in ADF-STEM
E. Oveisi, M. C. Spadaro, E. Rotunno +2
Competitive mechanisms contribute to image contrast from dislocations in annular dark field scanning transmission electron microscopy ADF STEM. A clear theoretical understanding of…
The role of 2s Bloch wave state excitations on STEM-HAADF intensity in quantitative analysis of alloys
Charlotte Wouters, Toni Markurt, Enzo Rotunno +2
In this work, we emphasize the important contribution of the 2s Bloch wave state to the properties of a STEM electron probe propagating on an atomic column. For a strong enough col…
Design of electrostatic phase elements for sorting the orbital angular momentum of electrons
Giulio Pozzi, Vincenzo Grillo, Peng-Han Lu +3
The orbital angular momentum (OAM) sorter is a new electron optical device for measuring an electron s OAM. It is based on two phase elements, which are referred to as the unwrappe…
Full-field mode sorter using two optimized phase transformations for high-dimensional quantum cryptography
Robert Fickler, Frédéric Bouchard, Enno Giese +3
High-dimensional encoding schemes have emerged as a novel way to perform quantum information tasks. For high dimensionality, temporal and transverse spatial modes of photons are th…
Orbital-angular-momentum-resolved electron magnetic chiral dichroism
Enzo Rotunno, Matteo Zanfrognini, Stefano Frabboni +4
We propose a highly efficient atomically-resolved mode of electron magnetic chiral dichroism. This method exploits the recently introduced orbital angular momentum spectrometer to…
Generation and Application of Bessel Beams in Electron Microscopy
Vincenzo Grillo, Jérémie Harris, Gian Carlo Gazzadi +6
We report a systematic treatment of the holographic generation of electron Bessel beams, with a view to applications in electron microscopy. We describe in detail the theory underl…
