Electron Pairs Precede High-Temperature Superconductivity
Like astronomers tweaking images to gain a more detailed glimpse of distant
stars, physicists at Brookhaven National Laboratory have found ways to sharpen
images of the energy spectra in high-temperature superconductors - materials
that carry electrical current effortlessly when cooled below a certain temperature.
These new imaging methods confirm that the electron pairs needed to carry current
emerge above the transition temperature, before superconductivity sets in, but
only in a particular direction.
