SCIENCE - Unique properties of two-dimensional crystal bring potential for optoelectronics, solar cells, valleytronics

When the dry lubricant, molybdenum disulfide, is stripped down to a single layer of atoms, a tightly bound quasi-particle comprised of two electrons and a hole forms with unique spin and valley properties, researchers from Case Western Reserve University and colleagues discovered.
