Yahachi Saito is an emeritus professor at Nagoya University, Japan. He received his doctorate in engineering from Nagoya University in 1980 and has held academic positions at Toyohashi University of Technology (1981-1985) and Mie University (1990-2004), Japan, in addition to Nagoya University (1985-1990, 2004-2018). He has also been a visiting scientist at AT&T Bell Laboratories, NJ, USA. He was a fellow at Toyota Physical and Chemical Research Institute, Aichi, Japan, from 2018 to 2022. Prof. Saito's area of expertise encompasses the synthesis, characterization, and application of nanometer-scale materials, especially inorganic atomic clusters, fullerenes, carbon nanotubes (CNTs), and graphene. He has studied CNT field emitters since 1996, collaborating with Noritake Itron Corp., Japan, since 1997 for the development of display devices using CNTs as a cold cathode. Prof. Saito is a recipient of several awards, including the Yazaki Arts and Science Award (2004), the Prize for Science and Technology of the Ministry of Education, Culture, Sports, Science and Technology (2006), the 2007 SID Distinguished Paper Award, and fellowship of the Japan Society of Applied Physics (2008). He has authored or co-authored 283 articles in international peer-reviewed journals and 6 books.
