Electron vortices in graphene detected

“Thanks to our extremely sensitive sensor and high spatial resolution, we didn’t even need to cool down the graphene...”

14-May-2024 - Researchers at ETH Zurich have, for the first time, made visible how electrons form vortices in a material at room temperature. Their experiment used a quantum sensing microscope with an extremely high resolution. When an ordinary electrical conductor – such as a metal wire – is connected to a ...
