Experimental Realisation of a π/2 Vortex Mode Converter for Electrons Using a Spherical Aberration Corrector
T. Schachinger, P. Hartel, P. -H. Lu +6
In light optics, beams with orbital angular momentum (OAM) can be produced by employing a properly-tuned two-cylinder-lens arrangement, also called /2 mode converter. It is not…
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…
Generation of electron vortices using non-exact electric fields
Amir H. Tavabi, Hugo Larocque, Peng-Han Lu +5
Vortices in electron beams can manifest several types of topological phenomena, such as the formation of exotic structures or interactions with topologically structured electromagn…
Highly Deformable and Mobile Palladium Nanocrystals as Efficient Carbon Scavengers
Peng-Han Lu, De-Gang Xie, Bo-Yu Liu +7
Fouling of surfaces leads to performance degradation in many energy-intensive industrial processes, but the present solutions are either too complicated to be routinely used or inc…
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…
Spherical aberration correction in a scanning transmission electron microscope using a sculpted foil
Roy Shiloh, Roei Remez, Peng-Han Lu +5
Nearly twenty years ago, following a sixty year struggle, scientists succeeded in correcting the bane of electron lenses, spherical aberration, using electromagnetic aberration cor…
