Computational ghost imaging for transmission electron microscopy
Akhil Kallepalli, Lorenzo Viani, Daan Stellinga +9
While transmission electron microscopes (TEM) can achieve a much higher resolution than optical microscopes, they face challenges of damage to samples during the high energy proces…
Alignment of electron optical beam shaping elements using a convolutional neural network
E. Rotunno, A. H. Tavabi, P. Rosi +4
A convolutional neural network is used to align an orbital angular momentum sorter in a transmission electron microscope. The method is demonstrated using simulations and experimen…
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…
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…
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…
Experimental demonstration of an electrostatic orbital angular momentum sorter for electrons
Amir H. Tavabi, Paolo Rosi, Giulio Pozzi +9
We report the first experimental demonstration of an electrostatic electron orbital angular momentum (OAM) sorter, which can be used to analyze the OAM states of electrons in a tra…
