Near-real-time diagnosis of electron optical phase aberrations in scanning transmission electron microscopy using an artificial neural network
Giovanni Bertoni, Enzo Rotunno, Daan Marsmans +4
The key to optimizing spatial resolution in a state-of-the-art scanning transmission electron microscope is the ability to precisely measure and correct for electron optical aberra…
Automatic alignment of an orbital angular momentum sorter in a transmission electron microscope using a convolution neural network
P. Rosi, A. Clausen, D. Weber +6
We report on the automatic alignment of a transmission electron microscope equipped with an orbital angular momentum sorter using a convolutional neural network. The neural network…
Symmetry and planar chirality of a protein measured on an angular basis in a transmission electron microscope
A. H. Tavabi, P. Rosi, R. B. G. Ravelli +16
In quantum mechanics, each conserved quantity (e.g., energy, position, linear momentum and angular momentum) is associated with a Hermitian operator. Its expected value can then be…
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…
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…
Towards a holographic approach to spherical aberration correction in scanning transmission electron microscopy
Vincenzo Grillo, Amir H. Tavabi, Emrah Yucelen +11
Recent progress in phase modulation using nanofabricated electron holograms has demonstrated how the phase of an electron beam can be controlled. In this paper, we apply this conce…
