Coherent regime of Kapitza-Dirac effect with electrons
Kamila Moriová, Petr Koutenský, Neli LaÅ¡toviÄková Streshkova +5
Electron matter waves coherently diffract when passing through a periodic structure of light formed by two interfering light waves. In this so-called Kapitza-Dirac effect, the elec…
Light-based electron aberration corrector
Marius Constantin Chirita Mihaila, Petr Koutenský, Kamila Moriová +1
Achieving atomic resolution in electron microscopy has historically been hindered by spherical aberration, a fundamental limitation of conventional electron lenses. Its correction…
Ultrafast 4D scanning transmission electron microscopy for imaging of localized optical fields
Petr Koutenský, Neli LaÅ¡toviÄková Streshkova, Kamila Moriová +4
Ultrafast electron microscopy aims for imaging transient phenomena occurring on nanoscale. One of its goals is to visualize localized optical and plasmonic modes generated by coher…
Design for light-based spherical aberration correction of ultrafast electron microscopes
Marius Constantin Chirita Mihaila, Martin Kozák
We theoretically demonstrate that ponderomotive interactions near the electron cross-over can be used for aberration correction in ultrafast electron microscopes. Highly magnified…
