Revolutionary way to tailor two dimensional sheet of electrons

16 May 2013

A research collaboration between Prof. Ariando and Prof. Venky Venkatesan at NanoCore, National University of Singapore, and collaborators from Japan, Sweden, China and The Netherlands have discovered a new 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. This discovery also opens 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.

This result has been published in Nature Communication.
