Abstracts:
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 feature of materials research is huge impact on our society if research is successful and meets the demands besides opening of new frontier in science.
We have studied electronic functionality in wide gap oxide-based materials over 30 years aiming at cultivation of new frontier in materials research. In this talk I introduce three excitements in our materials research interspersed with anecdotes, i.e.
(1)from discovery of iron-based superconductors to finding of advantageous grain boundary nature for wire fabrication [1,2].
(2)from basic idea of transparent amorphous oxide semiconductors as a novel class of amorphous semiconductors to their TFT application (IGZO) for flat panel displays (high resolution LCDs and large-sized OLED-TVs) and memory [3,4]
(3) from creation of stable electride and electrene, a material in which electrons serve as anions, to catalyst for green chemistry [5,6]
