Demonstration of a 2x2 programmable phase plate for electrons
Jo Verbeeck, Armand Béché, Knut Müller-Caspary +3
First results on the experimental realisation of a 2x2 programmable phase plate for electrons are presented. The design consists of an array of electrostatic einzel lenses that inf…
Exploring possibilities of band gap measurement with off-axis EELS in TEM
Svetlana Korneychuk, Bart Partoens, Giulio Guzzinati +4
A technique to measure the band gap of dielectric materials with high refractive index by means of energy electron loss spectroscopy (EELS) is presented. The technique relies on th…
Asymmetry and non-dispersivity in the Aharonov-Bohm effect
Maria Becker, Giulio Guzzinati, Béché Armand +2
Decades ago, Aharonov and Bohm showed that electrons are affected by electromagnetic potentials in the absence of forces due to fields. Zeilinger's theorem describes this absence o…
Theory and applications of free-electron vortex states
K. Y. Bliokh, I. P. Ivanov, G. Guzzinati +8
Both classical and quantum waves can form vortices: with helical phase fronts and azimuthal current densities. These features determine the intrinsic orbital angular momentum carri…
