(Nanowerk News) A German-Swedish team has succeeded in simultaneously studying the rapid motion of electrons with high spatial accuracy and a temporal resolution in the attosecond range. A ...

Characterization of the experimental setup. a) Schematic of the steps involved in the experiment. A pair of XUV pulses (drawn in violet) photoemits electrons from a ZnO crystal. The electrons ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.210011 considers defect dynamics at the buried interface revealed by photoemission electron microscopy. In recent years, LaAlO 3 ...

The new method sheds light on this puzzle. Wiebke Bennecke, physicist at the University of Göttingen and first author of the study, explains: "Using our photoemission electron microscope, we can ...

Free electrons are those not bound to a specific atom or molecule, wondering freely within a material. They play a vital role in a wide range of applications, from photoreactors and microscopes to ...

Schematic representation of the experimental setup: Attosecond pulses (violet) eject electrons (green) from a crystal surface. The photoemission electron microscope (cone-shaped instrument at top) ...
