Abstract：
The talk focuses on the group research efforts on various nanostructured functional oxide thin films for high temperature superconductors (HTS), solid oxide fuel cells, ferroelectrics, transparent conducting oxides and others. Wires that carry electrical current without resistance are fabricated by coating metal substrates with the HTS YBa2Cu3O7-δ (YBCO). Using nanolayer architecture and nano-particle doping approaches, YBCO coated conductors with dramatically enhanced transport properties can be achieved. Another way of nanoengineering is to process self-assembled vertical-aligned nanocomposite (VAN). We have successfully demonstrated several VAN systems. These VAN systems show interesting lattice epitaxial relationship along the vertical grain boundaries, which enables highly strained films with thickness higher than 100nm. Using VAN structure, enhanced ferroelectric and magnetrotransport properties have been achieved in several systems, and, highly efficient thin film cathodes with superior ionic conductivity can be made in thin film solid oxide fuel cells. Detailed microstructural characteristics of these nanostructured ceramic thin films will be discussed and correlated with their unique functionalities. Other research interests including in situ TEM and high resolution STEM analysis will be discussed.
