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…
Sum rules in zone axis STEM-orbital angular momentum resolved electron magnetic chiral dichroism
Matteo Zanfrognini, Enzo Rotunno, Jan Rusz +4
In this work we derive sum rules for orbital angular momentum(OAM) resolved electron magnetic chiral dichroism (EMCD) which enable the evaluation of the strength of spin and orbita…
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…
Orbital angular momentum and energy loss characterization of plasmonic excitations in metallic nanostructures in TEM
Matteo Zanfrognini, Enzo Rotunno, Stefano Frabboni +4
Recently, a new device to measure the Orbital Angular Momentum (OAM) electronic spectrum after elastic/inelastic scattering in a transmission electron microscope has been introduce…
