Focused Ion Beam fabrication of Janus bimetallic cylinders acting as drift~tube Zernike phase plates
Paolo Rosi, Gian Carlo Gazzadi, Stefano Frabboni +4
Modern nanotechnology techniques offer new opportunities for fabricating structures and devices at the micron and sub-micron level. Here, we use focused ion beam techniques to real…
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…
Exploring the spatial features of electronic transitions in molecular and biomolecular systems by swift electrons
Ciro A. Guido, Enzo Rotunno, Matteo Zanfrognini +2
Electron energy loss spectroscopy is consolidating as a powerful tool to explore electronic (as well as vibrational) excitations of matter, including molecules. Performed in a scan…
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…
Efficient molecule discrimination in electron microcopy through an optimized orbital angular momentum sorter
Filippo Troiani, Enzo Rotunno, Stefano Frabboni +4
We consider the problem of discriminating macromolecular structures in an electron microscope, through a specific beam shaping technique. Our approach is based on maximizing the wh…
