HMM: SCIENTISTS CREATE MATERIAL MADE ENTIRELY OUT OF ELECTRONS. “For the first time, scientists have managed to create and take images of a Wigner crystal: a bizarre material, made entirely out of electrons, that was first theorized 90 years ago. Scientists managed to arrange the electrons into a honeycomb-like lattice by sandwiching them in an electric field between two atom-thin layers of tungsten compounds, according to research published in the journal Nature last week. The ability to tame them — which scientists accomplished by exploiting the tiniest differences in the atomic structures of the two tungsten layers — marks an incredible experimental achievement that has, until now, eluded the most accomplished labs in physics.”
