An artist’s rendering of the thickness-driven, metal-insulator transition in sub-nanometer films of a lanthanum nickelate. Nickel atoms are shown in gold, oxygen atoms in white, and lanthanum atoms in red, and metallicity is achieved in going from two to three atomic layers.April, 2014: KIC members Kyle Shen, Darrell Schlom and Phil King and a team from Cornell and Brookhaven National Lab have discovered a new property of metal oxides that can act like a switch when the material is less than a nanometer thick.  The finding were published online April 6 in Nature Nanotechnology and will appear in the journal’s May issue.
