Either 1 or 0. Either current flows or it does not. In electronics, everything is controlled via the binary system. Electrons already generate information quite fast and well, pass them on and take over various switching functions. But it can be done even faster. Paul Herrmann and Sebastian Klimmer from the Friedrich Schiller University of Jena have proven that. To this end, the two doctoral students at the Institute of Solid State Physics have experimented with monocrystalline 2D materials and laser light. They combined the well-known physical method of frequency doubling of light with a special material property, valleypolarization, and achieved astonishing results. ...
