Short Bio

Hideo Hosono is an honorary and institute professor of Tokyo Institute of Technology and a distinguished fellow and a group leader at National Institute for Materials Science. He received a Ph.D. (thesis: electron spin resonance in oxide glasses) in Applied Chemistry from Tokyo Metropolitan University in 1982, and became a professor of Tokyo Tech in 1999 via Nagoya Tech, Institute for Molecular Science and Vanderbilt University.  He studied point defects in SiO2 glass and worked on creation of photosensitive glasses utilizing point defects, photonic glasses by ion implantation, protonic conductive glasses and micro-porous glass-ceramics with phosphate skeleton.  After these researches, he shifted his main subject to cultivation of electro-active functionality in transparent oxides since 1993. His research focus is creation of novel functional materials based on own design concept. The representative achievements so far are material design of transparent oxide semiconductors such as IGZO and their TFT applications for the state-of the art displays (OLED-TVs are driven by IGZO-TFTs), creation of stable electrides and their application to catalysts for ammonia synthesis, and discovery of high-Tc iron-based superconductors which led to the 2nd research fever since high-Tc cuprates.  Hosono is a recipient of various honors including the Japan Prize, von Hippel Prize (MRS), J. McGroddy Prize (APS), Jan Raychman Prize (SID), Eduard Rhein Award, Imperial Prize (the Japan Academy), and is a Thomson Reuter Citation Laureate and a foreign fellow of the Royal Society

Abstract body:

Materials science is a cross-disciplinary subject bridging physics and chemistry, and fundamental science and application engineering. This unique feature provides a variety of opportunities for social implementation of novel materials created in academia. The most fascinating thing in materials research is huge impact on our society if research is successful and meets with demands.

We have studied electronic functionality in wide gap oxide-based materials, which is a main ingredient of ceramics, over 20 years aiming at cultivation of new frontier in which fundamentals and applications. In this talk I introduce three excitements in my materials research., i.e. (1)from basic idea of transparent amorphous oxide semiconductors as a novel class of amorphous semiconductors to their TFT application (IGZO) in flat panel displays (high resolution& energy saving LCDs and large-sized OLED-TVs[1], (2) from creation of stable electride, a material in which electrons serve anions, to catalyst green ammonia synthesis [2], and (3) from discovery of iron-based superconductors to finding of excellent grain boundary nature advantageous for wire and bulk magnet fabrication [3].
