Epitaxial Film Growth and Some Applications of Functional Oxides
High-quality epitaxial films, which can be grown on well-aligned atomic arrangement, are essentially important to understand the intrinsic characteristics of solid materials. Here I will show you the techniques to fabricate high quality epitaxial films of functional oxides based on the pulsed laser deposition. I will also introduce several optoelectronic devices with three-terminal thin-film transistor structure fabricated on functional oxide epitaxial thin films.
About the Speaker
Professor, Research Institute for Electronic Science
Professor Hiromichi Ohta obtained his B.S. and M.S. degrees in Applied Chemistry from Saitama University and Nagoya University, respectively. Prior receiving his Ph.D. in 2001 from Tokyo Institute of Technology, he worked as a researcher in two companies: Sanyo Electric (1996-1997) and Hoya (1998-2003). At Sanyo Electric, he worked on lithium ion batteries. While he was at Hoya, his work involved in the development of transparent conducting oxides. In 1999, he was sent on loan to Hosono Transparent ElectroActive Materials Project. During his tenure, he developed transparent thin-film transistors using indium gallium zinc oxide (IGZO) semiconductors. This discovery was published in Science and Nature (over 5000 citations), and is currently applied in modern liquid crystal displays (LCD).
In 2003, he became an associate professor at Nagoya University, and in 2012, he became a full professor at the Research Institute for Electronic Science, Hokkaido University. His current research interests include oxide-based thermoelectric materials, oxide electronics, as well as thin film epitaxial growth techniques.
