Physicists have detected laser-assisted electron scattering using circularly polarized light for the first time, revealing new ways to probe atomic-scale chirality.

(Nanowerk News) Imagine standing by a lake and throwing a stone into the water. Waves spread out in circular patterns and can reflect at obstacles and boundaries. Researchers at the University of ...

Electron beam oscillators utilising surface wave structures represent a key technology in the generation of high‐power electromagnetic radiation. By deploying relativistic electron beams in ...

Scientists at the University of Konstanz in Germany have advanced ultrafast electron microscopy to unprecedented time resolution. Reporting in Science Advances, the research team presents a method for ...

(a) Ordinary electrons without wave shaping have a uniform wave pattern when they travel. In simulations, the electrons collide with the atoms in graphene (red spheres represent graphene atoms and ...

However, the most important point is the need to limit the influence of diffraction contrast to obtain accurate measurements. In this respect, the use of a plane electron wave for EH is clearly ...

Superradiance When multiple electrons emit light in a coordinated manner, the resulting emission is much stronger than the sum of individual emissions. (Courtesy ...

(b) The electrons are waveshaped using a waveshaping instrument, such as a phase plate, and they form regular wave patterns (green rings) that overlap with the positions of the graphene’s atoms (red ...
