Etch a Sketch Nanoelectronics

Electronic confinement at nanoscale dimensions remains a central means of science and technology I will describe a novel method for producing electronic nanostructures at the interface between two normally insulating oxides LaAlO3 and SrTiO3 Conducting nanostructures are written erased and reconfigured under ambient conditions at room temperature similar to the operation of an etch a sketch toy A wide variety of devices can be created including nanowires tunnel junctions diodes field effect transistors single electron transistors superconducting nanowires
