Collaborative research featured as Physical Sciences Division Research Highlight

Jan. 20, 2016 - CEMS researchers including Peng Xu, Jong Seok Jeong, K. Andre Mkhoyan, and Bharat Jalan and Timothy C. Droubay, Peter V. Sushko, Scott A. Chambers of Pacific Northwest National Laboratory (PNNL) had their research "Creating an Electrical Conduit Using Two Insulators" featured as a "Science Headline" on the U.S. Department of Energy Office of Science website and as a PNNL "Physical Sciences Division Research Highlight."

Revolutionary new electronic devices, such as those required for next-generation computers, require new and novel material systems. Scientists at the University of Minnesota and Pacific Northwest National Laboratory showed that combining two oxide materials in one particular orientation gives rise to a densely packed sheet of highly mobile electrons. The sheet is created when bound electrons jump across the junction of a neodymium-based oxide, NdTiO3, to a material based on strontium, SrTiO3, and become free. The density of these electrons -- the highest ever observed at the junction of two materials -- paves the way for a new class of electronic devices.
