Takeshi Yamao is a professor in the Faculty of Materials Science and Engineering at Kyoto Institute of Technology. He earned a Master of Engineering and a Doctor of Engineering from Kyoto Institute of Technology. His career at the institution spans multiple roles, beginning as a research fellow and assistant, advancing to associate professor, and assuming his current professorship in 2018. Yamao has contributed to research in the evaluation of photo- and electro-properties of organic functional materials and their device applications and development. He has authored or co-authored numerous peer-reviewed papers on topics including organic crystal light-emitting transistors, single-crystal growth methods, laser oscillation in organic materials, and properties of thiophene/phenylene co-oligomers and pyrene derivatives. Key publications include works on distributed feedback lasers fabricated on organic crystals and comprehensive studies of photophysical properties of organic co-oligomers. Yamao has served on committees for the Applied Physics Society and the Japan Society for the Promotion of Science, and as a director of the Solar Energy Utilization Promotion Association. He has participated in international conferences and contributed chapters to books on advanced organic semiconductor devices.
Throughout his tenure, Yamao has focused on advancing organic optoelectronic devices, including light-emitting field-effect transistors and microcavity structures. His work has involved collaborations on perovskite materials, polyaniline hole transport layers, and friction-transferred organic semiconductor films. No major awards or fellowships are documented in official profiles. Yamao maintains an active research program with recent publications addressing charge transport in halogen-substituted pyrenes and photoinduced phase segregation in halide perovskites.
