Physicists at the Universities of Regensburg and Marburg and Forschungszentrum Jülich tracked electrons leaping across forbidden energy gaps in graphene, with some transitions reaching 100 percent probability. Scientists captured electrons jumping across forbidden energy gaps in graphene, with some transitions occurring at 100% probability. Using a new slow-motion electron camera, a photoemission momentum microscope combined with intense light pulses, the team watched electrons switch between energy bands. ScienceDaily reported that the leaps are analogous to an elevator skipping seventeen floors, and that the transitions, known as Landau-Zener-Majorana transitions, were published in Nature. Rupert Huber said the team spent many years on the experiment and can now track electrons across the energy landscape of a solid in real time. The graphene samples, made at Forschungszentrum Jülich, were one atom thick and nearly flawless, which helped separate the quantum effects from imperfections. The result offers a close look at quantum behavior and could support ultrafast, light-controlled electronics.
