Search for ternary hydrides with high-Tc superconductivity near room temperature
Some materials that do not exhibit superconductivity at ambient pressure can become superconductors by applying pressure. Among them, hydrogen and hydrogen-rich materials were expected to become high-temperature superconductors under high pressure. Recently, binary hydrogen compounds such as hydrogen sulfide and lanthanum super-hydride were discovered to become high-temperature superconductors under ultrahigh pressure exceeding 100 GPa, greatly breaking the previous record for superconducting transition temperature.
In this study, I aim to synthesize new ternary hydrides and discover new high-temperature superconductors with superconducting transition temperatures approaching room temperature.


I would like to express my sincere gratitude to the Inamori Foundation for selecting me for the Inamori Foundation Research Grant.
In this study, two pairs of very high quality brilliant-cut diamonds of about 0.2 carat are used to apply pressure. The material is pressurized between the culet of the diamonds, which is a very small area to generate ultrahigh pressure, so the sample size is about 5 microns, making this an artisanal experiment. Also, diamonds are consumable because they break under ultrahigh pressure. I believe that the support of this research grant will allow me to further advance my research.
