Element Strategy in Materials Research
The Materials Research Society's highest honor, the Von Hippel Award, is conferred annually to an individual in recognition of the recipient's outstanding contribution to interdisciplinary research on materials.
“for the discovery of high Tc iron-based superconductors, creation of transparent oxide semiconductors and inorganic electrides"
The function of material is inseparably related with the nature of constituting elements. However, existing elements are only about 100, and the number of elements that can actually be used for materials is limited to 60–70 because of their scarcity and toxicity. Therefore, it is a grand challenge in materials science to realize valuable functionality fully utilizing abundant elements. I have concentrated on the cultivation of electro-active functionality in oxide-based materials over the past two decades. Three highlights of these achievements are the discovery of iron-based high-Tc superconductors and the creation of transparent oxide semiconductors (especially amorphous oxide semiconductors with high mobility for TFTs) and inorganic electrides. To my interest, these three materials are based on the main component of modern buildings, iron, glass, and cement. In this talk, I review these researches and suggest the hidden potential of abundant elements in materials research.
About Hideo Hosono
Hideo Hosono earned a PhD degree in applied chemistry from Tokyo Metropolitan University in 1982. He became a professor at the Tokyo Institute of Technology (Tokyo Tech) in 1999, after working as an associate professor at Nagoya Institute of Technology, National Institute for Molecular Science, and Tokyo Tech. He was the Founding Director of the Materials Research Center for Element Strategy in 2012. Hosono is a Foreign Fellow of The Royal Society, London, and a member of university councilors.
Hosono created IGZO semiconductors and their TFTs, which are now applied as the backplane of large-sized OLED-TVs. In 2008, his group discovered a high-Tc iron-pnictide superconductor, which has now grown to a continent of high-Tc superconductors comparable to cuprates. He is a pioneer of stable electride and 2D electrides and their applications represented by catalysts for ammonia synthesis.
Hosono has received numerous awards and honors, including the Medal of Honor (Purple Ribbon), Bernd T. Matthias Prize, Jan Rajchman Prize, Thomson Reuters Citation Laureate, James C. McGroddy Prize for New Materials, Imperial Prize, Japan Academy Prize and the Japan Prize.
