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…
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…
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…
Measuring an electron beam's orbital angular momentum spectrum
incenzo Grillo, Amir H. Tavabi, Federico Venturi +12
Quantum complementarity states that particles, e.g. electrons, can exhibit wave-like properties such as diffraction and interference upon propagation. \textit{Electron waves} defin…
Generation and Application of Bessel Beams in Electron Microscopy
Vincenzo Grillo, Jérémie Harris, Gian Carlo Gazzadi +6
We report a systematic treatment of the holographic generation of electron Bessel beams, with a view to applications in electron microscopy. We describe in detail the theory underl…
Convergent beam electron-diffraction investigation of lattice mismatch and static disorder in GaAs/GaAs1-xNx intercalated GaAs/GaAs1-xNx:H heterostructures
Stefano Frabboni, Vincenzo Grillo, Gian Carlo Gazzadi +8
Hydrogen incorporation in diluted nitride semiconductors dramatically modifies the electronic and structural properties of the crystal through the creation of nitrogen-hydrogen com…
