Thin films and nanostructures are the basis for modern microelectronics and other applications. Growth and characterization of thin films and nanostructures have 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 and nanostructures (quantum dots, nanotubes, nanowires, graphene and other 2D atomic materials) of semiconductors, superconductor, ferroelectric and magnetic materials, etc. With continuous downsizing of electronic devices into a few nanometer regime as predicted by the Moore’s law, controlling materials and interfaces at atomic scales becomes a prominent research topic and has been the current focus of our research that has impacts on various applications including Josephson tunnel junctions, memristors, photodetectors, sensors, etc.
