Researchers Explain Unusual Properties of Semiconductor Materials

The Ohio State University scientists have offered an initial theory as how the properties of two materials unexpectedly change when layered together. The materials lanthanum aluminate and strontium titanate are fairly unexciting until they are sandwiched together. Then, they are both conductive and magnetic. These properties were initially discovered in 2004, but no explanation for how they interact at their interface was offered until now. Understanding how these materials work together could enable researchers to invent new forms of integrated computational and data storage devices, say the researchers. It could also lead to the exploration of other oxide material combinations. This research was published in the journal Nature Physics. (EurekAlert)(The Ohio State University)(Nature Physics)
