Electrons have potential for mutual attraction

Nanotube system overcomes natural repulsion in possible step toward advanced superconductors

ELECTRONS ATTRACT Although electrons normally repel one another, a new study shows that two electrons (green in this illustration) can attract, thanks to their repulsion from other electrons (purple).

Standoffish electrons typically keep one another at arm’s length, repelling their neighbors. But surprisingly, under certain circumstances, this repulsion can cause pairs of electrons to soften their stance toward one another and attract instead, new research shows. The effect may be the key to someday producing a new type of high-temperature superconductor, scientists report in the July 21 Nature.
