Title: Theme 1: Quantum Materials


1
Theme 1 Quantum Materials
  • Leaders George Crabtree (ANL) / Thomas
    Rosenbaum(UC)
  • Goal to develop next generation materials,
    with unique electronic, magnetic or optical
    responses through tailoring quantum-mechanical
    properties on nanometer scales
  • Opportunities

New classes of nanoscale hybrids
  • conductors / superconductors
  • magnetic storage materials
  • spin-based logic elements (spintronics)

Theme 2 Nano-Bio Composite Structures
  • Leaders Tijana Rajh (ANL) / Laurens Mets (UC)

Goal to combine selective molecular recognition
properties of biological macromolecules (nucleic
acids and proteins) with functional properties of
nano-scale particulate materials.
Opportunities
INFORMATICS
STRUCTURE
Nanomolecular tagging
Nanoscaffolds
Genome mapping Gene sequencing Intracellular
mapping
Structural studies of biomolecular assemblies
MANIPULATION OF FUNCTION
Multifunctional nanomachines
Intracellular manipulation, gene therapy,
biosensors complex functional materials

Theme 3 Adaptive Nanoscale Self-Assembly
  • Leaders Sam Bader (ANL) / Steven Sibener (UC)

Goal to create nanostructures with novel
chemical or physical function using self-assembly
processes.
Opportunities
Self-assembly is a massively parallel process
intrinsically simpler, faster, and less costly
than conventional methods
Can cover the difficult range from 100nm down to
atomic scale
  • New directions
  • hierarchical templating
  • off-equilibrium paths

adaptive self-assembly

Self-Assembly
  • Magnetic nanowires (Bader)

Fe on stepped curved Pd(110)
Electro-active copolymers (Yu)
Hierarchical, adsorbate-mediated templating
(Sibener)
Xe/H/Ni(977)

Theme 4 Nanophotonics
  • Leaders Norbert Scherer (UC) / Gary Wiederrecht
    (ANL)

Goal to develop strategies for transmitting and
manipulating optical information on
sub-wavelength scales.
Opportunities
New classes of optically active materials
  • Controlled ultrashort pulse propagation
  • Novel behavior from interplay of electronic and
    optical properties (-gt switches)
  • New types of optical computing elements
