Within LiMatI project S05 a study on the generation and measurement of the shortest electron pulse to date was published in Nature (Kim et al., Nature 613, 662-666 (2023)). The pulse was generated using lasers to release electrons from a tiny metal tip and lasted only 53 attoseconds, that is 53 billionths of a billionth of a second. The study sets a new speed record in man-made control of electric currents in solid materials and opens new possibilities for improving the performance of electronics and information technologies, as well as for developing new scientific methods for visualizing phenomena in the microcosm at ultimate speeds.
