“Optical fingerprints” on an electron beam

Researchers observe non-linear optical processes in the electron microscope

17-Jan-2024 - The precise control of electron beams in so-called transmission electron microscopes (TEM) makes it possible to analyze materials or molecules at the atomic level. Combined with short light pulses, these devices can also be used to analyze dynamic processes. Researchers from Göttingen and ...

Tailored electron pulses for improved electron microscopy

Interplay of free electrons

16-Oct-2023 - Electron microscopes provide unique vistas of nanoscale structures, but their resolution is limited by the mutual repulsion of electrons. Researchers in Göttingen have now succeeded in precisely measuring the influence of these interactions. They discovered an “energetic fingerprint” in which the ...

An ultrafast microscope for the quantum world

28-Jan-2020 - Processes taking place inside tiny electronic components or in molecules can now be filmed at a resolution of a few hundred attoseconds and down to the individual atom. The operation of components for future computers can now be filmed in HD quality, so to speak. Manish Garg and Klaus Kern, ...

Novel 3D printed polymer lenses for X-ray microscopes: highly efficient and low cost

07-Sep-2018 - Scientists at the Max Planck Institute for Intelligent Systems in Stuttgart invented a new and cost-effective method for making X-ray lenses with nanometer-sized features and excellent focusing capabilities. By using an advanced 3D printing technique, a single lens can be manufactured under a ...
