BNL Wins Two R&D 100 Awards for Imaging Devices

UPTON, NY — The U.S. Department of Energy’s (DOE) Brookhaven National Laboratory has won two R&D 100 Awards for developing imaging tools that will help researchers study materials ranging from seventeenth-century paintings to photovoltaics. The new devices promise to unlock scientific secrets with greater depth and coverage...link

Engineering Atomic Interfaces for New Electronics

At Brookhaven National Laboratory’s Center for Functional Nanomaterials and the Department of Condensed Matter Physics and Materials Science, scientists Yimei Zhu and Dong Su simultaneously examined the crystal structure and electron structure of the interfaces in an atom-by-atom fashion based on ultra-high-resolution imaging and spectroscopy. These studies helped the multi-institutional team discover that the addition of a single layer of atoms at an oxide interface can drastically alter the conductivity of the material, from highly conductive to completely insulating, depending on the element used. In particular, Brookhaven scientists played a key role in revealing the origin of an electron “gas” that forms at the interface...
