ORNL materials researchers get first look at atom-thin boundaries
November 10, 2014 — OAK RIDGE, Tenn., Nov. 10, 2014—Scientists at the Department of Energy’s Oak Ridge National Laboratory have made the first direct observations of a one-dimensional boundary separating two different, atom-thin materials, enabling studies of long-theorized phenomena at these interfaces.
Good vibrations give electrons excitations that rock an insulator to go metallic
November 10, 2014 — OAK RIDGE, Tenn., Nov. 10, 2014—For more than 50 years, scientists have debated what turns particular oxide insulators, in which electrons barely move, into metals, in which electrons flow freely. Some scientists sided with Nobel Prize–winning physicist Nevill Mott in thinking direct interactions between electrons were the key.
