Post-Silicon Computing
A tiny 'toy' with big potential could transform the way computing is done, thanks to a grant from NSF to Pitt and partner universities
PITTSBURGH—Could Pittsburgh be the nation's next "Strontium Valley"? The University of Pittsburgh is the lead institution on a $1.8 million grant from the National Science Foundation and the Nanoelectronics Research Initiative (NRI) of the Semiconductor Research Corporation (SRC) to bring a new kind of computer out of the lab and into the real world. The goal of the group, led by Jeremy Levy, a professor of physics and astronomy in Pitt's School of Arts and Sciences, is no less than transforming the way computing is done.
This book chapter reviews the experimental evidence for magnetic phenomena at the LaAlO 3 /SrTiO 3 interface. We argue that essentially all of the signatures of magnetism can be sorted into two distinct categories: (1) magnetic phases (e.g., ferromagnetic or Kondo)...
The interface between LaAlO 3 and TiO 2 -terminated SrTiO 3 can be switched between metastable conductive and insulating states using a conductive atomic force microscope probe. Determination of the nanoscale dimensions has previously required a destructive readout (e.g., local restoration...
Reports of emergent conductivity, superconductivity and magnetism have helped to fuel intense interest in the rich physics and technological potential of complex-oxide interfaces. Here we employ magnetic force microscopy to search for room-temperature magnetism in the well-studied LaAlO 3 /SrTiO 3...
