A new way to control oxygen for electronic properties
Lemont IL (SPX) Jun 14, 2016
Hotel managers and materials scientists have a lot in common - they both need to find a way to control properties by managing vacancies. Researchers at the U.S. Department of Energy's Argonne National Laboratory found they could use a small electric current to introduce oxygen voids, or vacancies, that dramatically change the conductivity of thin oxide films. The results are published in Nature Communications. The discovery improves our understanding of how these materials work and could be useful ... read more
