Thin films are the basis for modern microelectronics and a large number of technologies Thin films are also one of the most important tools for the preparation of novel materials. Although application oriented, growth and characterization of thin films has been an important subject for both basic and applied physics research. The focus of our research is on growth , characterization, and applications of various thin films including superconductor, ferroelectric and magnetic materials. While the size of electronic devices continuously decreasing into nanometer regime as predicted by the Moore?s law, nanoscience has emerged as one of the most prominent research areas in the 21st century. One of our new research focuses has been on growth of various nano-matters including nano-particles and nanowires, and development of characterization tools for nano-matter study.
