In the new “bottom-up” paradigm for nanoelectronics there is a need for novel, nanoscale building blocks. With regard to integration, the new “bottom up” approach is likely to sidestep the processing compatibility problems associated with the conventional “top down” approach because the building blocks can be synthesized in isolation, prior to their assembly into circuits. The first objective of my research is to create novel building blocks of metal-oxide-metal (MOM) nanowires, with 50-100 nm diameter and 1-10 microns in length (figure below). The metal will be Au or Pt, and the functional oxide will be barium titanate (ferroelectric and/or piezoelectric) or rare-earth manginites (magneto-resistant). The new MOM nanowires offer the rare opportunity of directly measuring the functional properties of nano-scale functional oxides. Nanocircuits will be fabricated with MOM nanowires using focused ion beam lithography (FIB), electron beam lithography, or complementary self-assembled monolayers (SAMs) methods. The second objective of my research will then be to measure the individual and coupled functional properties (resistivity, ferroelectric response, piezoelectric response, dielectric constant, magneto-resistance) of these nanocircuits under various conditions. Finally, structure-property relations in these MOM nanowires will be established.
