Hideo Hosono

Hideo Hosono is a Japanese materials scientist and professor at the Tokyo Institute of Technology, internationally recognized for his work in solid-state chemistry. He pioneered the development of transparent oxide semiconductors. Most notably, he created the IGZO (indium gallium zinc oxide) material that is now widely used in modern displays.

The IGZO material developed by Hosono is a transparent semiconductor that is widely utilized in liquid crystal displays (LCDs) and organic light-emitting diode (OLED) screens. It allows displays to have higher resolutions, faster refresh rates, and significantly lower power consumption. It is currently used in millions of smartphones, tablets, and televisions globally.

Yes, in addition to transparent semiconductors, Hosono also pioneered the discovery of iron-based superconductors in the mid-2000s. These materials, specifically lanthanum iron arsenic oxides, surprised the scientific community as they superconduct at relatively high temperatures. This opened up an entirely new field of study in condensed matter physics.

Hideo Hosono conducts his research at the Tokyo Institute of Technology. He specifically leads initiatives at the Materials Research Center for Element Strategy. His laboratory focuses on utilizing ubiquitous, non-toxic elements to create advanced electronic materials.
