Unexpected conductivity

The Science Magazine selected a research by Prof ARIANDO from the Department of Physics and highlighted under the Editor’s Choice on 14 June 2013.


The discovery revealed a revolutionary way to tailor two dimensional sheet of electrons along specific crystallographic orientation at the interface of insulating oxide systems. This has led to a direction dependent conducting behavior with potential for directional superconductivity and magnetism leading to possible new science and applications. The discovery also open-up a new pathway for creating nanoscale one dimensional conducting wires, which is of importance for understanding the physics of low dimensional systems and for developing nanoscale devices in this bilayer oxide system.


Their findings have been published in Nature Communication.
