Research Interest

    My research interests focus on the thin film growth mechanism and structural properties of ultra-thin epitaxial films and various nano-materials. The major experimental tools are x-ray scattering and scanning probe microscopy. In the recent years, my group has been working on several subjects including:The crystal structure and interfacial atomic arrangement of epitaxial films of various metal oxides, especially high-k oxide for gate oxide application. The study provides valuable data to examine various thin film growth mechanisms and the role of interfacial chemistry. 

  The structural and optical properties of ZnO-based epitaxial optoelectronic thin film materials with particular emphasis on the defect structures, strain state and their influence to the optical and electrical performance of these epi-films. The growth of high quality polar and non-polar ZnO epitaxial films and multi-layers on various substrates is a focus of recent studies. Pulsed laser deposition, and RF sputtering growth are employed to fabricate the samples. The structure and composition characterization of various novel nano-materaials. Besides the subjects mentioned above, we have also involved in structural investigation of various novel thin film materials and developing new experimental techniques for structural and compositional characterization.
