Prof. Shinji Koh received his BS (1995), MS (1997), and Dr. degree of Engineering (2000) from the University of Tokyo. After 4 years at the University of Tokyo and 3 years at the Tohoku University as a research associate, he started a faculty career as an associate professor in Nara Institute of Science and Technology (NAIST) in 2007. In 2013, he joined to Aoyama Gakuin University as an associate professor and was promoted to full professor in 2018. His research fields include crystal growth and device application of electronic and photonic materials.

Graphene has attracted attention owing to its unique properties and possibilities for numerous practical device applications. Chemical vapor deposition (CVD) growth is a promising way to synthesize high-quality and large-area graphene sheets. We demonstrated CVD growth of single-crystal monolayer graphene on Ir(111)/sapphire substrates, and the reuse of the same substrates in multiple CVD growth. Prof. Shinji Koh will also introduce his recent device applications of the large-area CVD graphene sheets including optically transparent dipole antennas operating at 20 GHz, luminescent graphene and free residual chlorine sensor based on graphene field effect transistors.
