SUMMARY:Correlated Nanoelectronics\, R. G. Herb Condensed Matter Semin
 ar\, Jeremy Levy\, University of Pittsburgh
DESCRIPTION:The study of strongly correlated electronic systems and th
 e development of quantum transport in nanoelectronic devices have foll
 owed distinct\, mostly non-overlapping paths.  Electronic correlations
  of complex materials lead to emergent properties such as superconduct
 ivity\, magnetism\, and Mott insulator phases.  Nanoelectronics genera
 lly starts with far simpler materials (e.g.\, carbon-based or semicond
 uctors) and derives functionality from doping and spatial confinement 
 to two or fewer spatial dimensions.  In the last decade\, these two fi
 elds have begun to overlap.  The development of new growth techniques 
 for complex oxides have enabled new families of heterostructures which
  can be electrostatically gated between insulating\, ferromagnetic\, c
 onducting and superconducting phases.   In my own research\, we use a 
 scanning probe to “write” and “erase” conducting nanostructure
 s at the LaAlO3/SrTiO3 interface.  The process is similar to that of a
 n Etch-a-Sketch toy\,  but with a precision of two nanometers.  A wide
  variety of nanoscale devices have already been demonstrated\, includi
 ng nanowires\, nanoscale photodetectors\, THz emitters and detectors\,
  tunnel junctions\, diodes\, field-effect transistors\, single-electro
 n transistors\, superconducting nanostructures and ballistic electron 
 waveguides. These building blocks may form the basis for novel technol
 ogies\, including a platform for complex-oxide-based quantum computati
 on and quantum simulation.
