Researchers Invent ‘Sideways’ Approach To 2-D Hybrid Materials
2014-01-10 14:06:22

Oak Ridge National Laboratory Researchers at the Department of Energy’s Oak Ridge National Laboratory and the University of Tennessee, Knoxville have pioneered a new technique for forming a two-dimensional, single-atom sheet of two different materials with a seamless boundary. The study, published in the journal Science, could enable the use of new types of 2-D hybrid materials in technological applications and fundamental research. By rethinking a traditional method of growing...

Microscopy Explores Nanowires' Weakest Link
2012-02-14 04:54:25

Individual atoms can make or break electronic properties in one of the world's smallest known conductors–quantum nanowires. Microscopic analysis at the Department of Energy's Oak Ridge National Laboratory is delivering a rare glimpse into how the atomic structure of the conducting nanowires affects their electronic behavior. The ORNL team's microscopy confirmed that deliberately introduced defects, which are only the size of a single atom, could turn a conducting nanowire into an...
