Scientists at the University of Regensburg and the Scuola Normale Superiore de Pisa have devised an ultrafast switch for electron waves, which could allow them to speed up future electronics many times over.
The characteristic shine of metals is created by electrons which can freely move in the interior of the material and reflect incoming radiation. Similar to water waves on a pond, waves can form on the surface of this electron sea – so called “surface plasmons”. Instead of a stone that is thrown into water, light is used to generate surface plasmons in the laboratory.
