Nanoengineering in Functional Oxide Thin Films

Haiyan Wang

Electrical & Computer Engineering, Texas A&M University, College Station, Texas

The talk focuses on our group’s research efforts on various nanostructured functional oxide thin films for high temperature superconductors (HTS), solid oxide fuel cells, 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 vertically aligned nanopore structure, 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.

Bio of Prof. Wang:

Dr. Haiyan Wang is an associate professor at Texas A&M University (TAMU). From December 2002 to January 2006, Wang was on the staff of the Los Alamos National Laboratory first as a post-doctoral fellow and then a technical staff member. She joined TAMU as an assistant professor in January 2006 and was promoted to associate professor in September 2010. She holds a Bachelor of Science degree from Nanchang University (China, 1998) and a master’s degree from the Institute of Metal Research (China, 1999). She received the Ph.D. degree in materials science and engineering from North Carolina State University in 2002. She is the PI of the Functional Thin Film Processing and Characterization Group at TAMU. Her group research interests lie in the area of functional oxide and nitride thin films for microelectronics, optoelectronics, high-temperature superconductors, solid oxide fuel cells, radiation tolerance materials and structural applications. She has authored and coauthored over 170 journal articles and 100 conference presentations. Her major awards include TEES Young Fellow Award 2010, NSF CAREER Award 2009, Presidential Early Career Award 2008 (PECASE), Office of Naval Research-Young Investigator Award 2008 and Air Force of Scientific Research-Young Investigator Award 2007.
