My research has spanned over areas including the physics of electronic thin films, surface science and interface phenomena, nanostructures and nanophenomena, advanced materials, nano/micro scale characterizations, and novel device fabrications. Details are:

• Thin Film Epitaxy and Materials Physics: Heteroepitaxy of complex oxide thin films and functional materials, Structure-Interface-Property-Processing interrelationships, epitaxial mechanisms, transport properties, strong correlation and multiferroic materials, highly epitaxial crystalline advanced thin films for microwave wireless communications, structural health monitoring systems, optoelectronic system, and nano/microelectromechanical systems (N/MEMS).

• Nano Advanced Materials Processing and Characterizations: self-assembled oxide nanostructures, growth dynamics and quantum effects, nanoscale characterizations and nanoscale transport properties, and highly ionic conductive oxide nanostructures for energy device applications such as solid state fuel cells and sensors.

• Interface Structures and Quantum Phenomena:
  Atomic dynamics and growth behavior on surface, interface and domain structures, size and interface strain effects, surface step terrace induced antiphase domain boundary and structure, transport properties at low dimensional systems, microstructure characterizations by using x-ray diffraction, electron microscopy, and scanning probe microscopy.
