A material that could enable faster memory chips and more efficient batteries can switch between high and low ionic conductivity states much faster than previously thought, SLAC and Stanford researchers have determined. The key is to use extremely small chunks of it.
A team led by SLAC and Stanford scientists has made an important discovery toward understanding how a large group of complex copper oxide materials lose their electrical resistance at remarkably high temperatures.
The materials in question are high-temperature superconductors, which conduct electricity perfectly with no resistance when cooled below minus 100 degrees Celsius.
Menlo Park, Calif. — Researchers using the Linac Coherent Light Source (LCLS) at the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory have found a way to strip most of the electrons from xenon atoms, creating a “supercharged,” strongly positive state at energies previously thought too low.
Condensed-matter physicists the world over are in hot pursuit of a comprehensive understanding of high-temperature superconductivity, not just for its technological benefits but for the clues it holds to strongly correlated electron systems.
An international team of researchers has used SLAC’s Linac Coherent Light Source (LCLS) to discover never-before-seen behavior by electrons in complex materials with extraordinary properties.
