Thin film growth and characterization for solid oxide fuel cells, mutiferroics, and superconductors.

Specifically, his current projects are:

• Strain engineering of ferroelectrics: enhanced ferroelectricity of BTO by
  epitaixal strain and superlattice structure
• Free-standing multiferroic BiFeO3 films
• YBCO-based coated conductors
• Thin-film oxide heterostructures for solid oxide fuel cells
