Electrons on a rapid journey through a crystal lattice

How fast do electrons whiz through the atomic layers of a crystal lattice? A team of scientists led by researchers from the Technische Universität München (TUM) joined by colleagues from the Max Planck Institute of Quantum Optics (MPQ), the Ludwig- Maximilians-Universität Munich and the Technical University of Vienna has now investigatigated this fundamental question. The researchers measured the time electrons needed to travel through a film consisting of a few layers a of magnesium atoms.
