First glimpse of hydrodynamic electron flow in 3D materials

"Really to "see" electrons flowing through a thin piece of metal like water through a pipe is very exciting"

29-Sep-2021 - Electrons flow through most materials more like a gas than a fluid, meaning they don’t interact much with one another. It was long hypothesized that electrons could flow like a fluid, but only recent advances in materials and measurement techniques allowed these effects to be observed in 2D ...

Enantiomorph distribution maps for metals and metallic alloys

07-Jun-2021 - The spatially resolved determination of which of the two enantiomorphic structural variants - the left-handed or the right-handed - of a chiral phase is present in a polycrystalline material is the focus of a publication in Science Advances. With the EBSD (electron backscatter diffraction) -based ...

Charge order and electron localization in a molecule-based solid

23-Jan-2018 - Charge ordering in cationic mixed-valence compounds is of crucial importance for materials science. The prototypic example for a transition from a charge-disordered to a charge-ordered state has been magnetite, Fe3O4, where Evert Verwey observed a sudden jump in resistivity near -150°C. In the ...

Gold: Rewriting text book knowledge

14-Jan-2016 - Gold as an element is known and highly valued for more than 2500 years, and its popularity is based on its beautiful color and chemical inertness. It is well established that the golden color is, physically spoken, of relativistic origin. The surface of gold is unique, as it hosts states that ...

Tunnel view of how electrons play

Scanning tunnelling microscopes provide insights into mysterious electronic effects in some metals

24-Jun-2011 - Electrons behave like football teams: the match becomes interesting when the teamwork is as good as that conjured up by the players of FC Barcelona. Electrons which interact strongly with each other give rise to superconductivity, the lossless transport of current, for example. A team headed by ...
