Title Nanotubes help engineer attractive electrons Degree of recognition International Media name/outlet nanotechweb.org Media type Web Date 22/07/2016 Description Electrons normally repel each other. This basic property may change, however, in certain solids such as superconductors, in which electrons coupled to lattice vibrations (or phonons) attract each other, forming bound pairs that then travel freely together through the material. Now, researchers in Israel, Germany, the US and Denmark have observed another type of “excitonic” electron attraction that does not involve phonons but actual repulsion between electrons. This mechanism, first predicted 50 years ago, but never yet seen in a laboratory experiment, could help make stronger and more exotic superconductors and be used to study the fundamental physical properties of these structures.

An experiment now confirms a fifty-year-old theory that electrons can also attract one another as a result of repulsion from other electrons.
