ORNL study reveals new characteristics of complex oxide surfaces
Date:7/24/2014

OAK RIDGE, Tenn., July 24, 2014 -- A novel combination of microscopy and data processing has given researchers at the Department of Energy's Oak Ridge National Laboratory an unprecedented look at the surface of a material known for its unusual physical and electrochemical properties.

The research team led by ORNL's Zheng Gai examined how oxygen affects the surface of a perovskite manganite, a complex material that exhibits dramatic magnetic and electronic behavior. The new avenue to understand surface behavior could benefit researchers who are interested in using a wide range of correlated oxide materials for applications such as solid fuel cells or oxygen sensors.

"Surface properties are key for any sensitive application, because the surface controls the interaction with the outside world," said coauthor Art Baddorf.

The team's results, published in Nature Communications, underscore why the materials are called "strongly correlated:" Because the chemical and physical functionalities are coupled, any minor change can influence the entire system.

"It's like the material has many knobs, and if you turn one, all the properties change," Gai said. "You turn a different knob and the whole thing changes again. It turns out the surface is another knob -- you can use it to change the properties."

The researchers used high-resolution scanning tunneling microscopy to generate images of the manganite surface -- down to the level of 30 picometers. A picometer is one trillionth of a meter. They then processed the imaging data to determine the position of each atom and calculate the angles between the atoms.

"Knowing where the atoms are positioned shows how they are interacting," Baddorf said.

The resulting "distortion maps" brought into view structural areas called domains that were not easily identified in the raw images. The maps clearly showed how the presence of oxygen atoms forced the atoms in
