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…
Theoretical and practical aspects of the design and production of synthetic holograms for transmission electron microscopy
Paolo Rosi, Federico Venturi, Giacomo Medici +10
Beam shaping - the ability to engineer the phase and the amplitude of massive and massless particles - has long interested scientists working on communication, imaging and the foun…
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…
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…
Phase retrieval of an electron vortex beam using diffraction holography
Federico Venturi, Marco Campanini, Gian Carlo Gazzadi +6
In both light optics and electron optics, the amplitude of a wave scattered by an object is an observable that is usually recorded in the form of an intensity distribution in a rea…
Realization of electron vortices with large orbital angular momentum using miniature holograms fabricated by electron beam lithography
E. Mafakheri, A. H. Tavabi, P. -H. Lu +9
Free electron beams that carry high values of orbital angular momentum (OAM) possess large magnetic moments along the propagation direction. This makes them an ideal probe for meas…
