Uncovering unique properties in a 2-dimensional crystal - 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. The charged quasi-particles offer potential use in new solar cells and other electronic devices that are controlled by light or designed to control light, to study what physicists call "many-body interactions"and a new concept of electronics called valleytronics. http://www.eurekalert.org/pub_releases/2012-12/cwru-uup120312.php
