The reporter learned from the Chinese Academy of Sciences Hefei Institute of Materials Science and Technology on the 21st that the Institute of Solid State Physics Research Institute of Extreme Environment Quantum Center, in cooperation with experts from the Italian National Institute of Optics, successfully synthesized a new hydride of selenium. The hydride is a potential high-temperature superconductor and is of great significance for the study of superconductivity. This research result was published online in the famous international journal Physical Review B. In recent years, an important event in the field of condensed matter physics was the discovery at 203K of hydrogen sulfide systems with superconductivity. Selenium as a main element of sulfur, selenium hydrogen system has also attracted wide attention. Previously, there were several high-temperature superconductors in the selenium-hydrogen system that were predicted by research institutions through first-principles and density functional theory. However, these types of materials do not exist in nature, and therefore these types of synthesized material is a hydrogen selenide Selenium hydrogen SUPERCONDUCTIVITY prerequisite. The research team of the Institute of Solid State Physics used diamond high-pressure anvil technology to change the interaction between molecules through external pressure, and combined with laser heating technology to induce chemical reaction of selenium and hydrogen in the pressure cavity, successfully synthesize new hydride of selenium. The study found that when the pressure exceeds 5 GPa, the high pressure chamber selenium - hydrogen Raman spectrum showing a new selenium - hydrogen and hydrogen - the hydrogen vibration modes, the vibration mode and which varies with pressure. High pressure synchrotron X-ray diffraction analysis, the new selenium hydride theoretical predictions have special space group of novel hydride. The hydride can be stable to at least 40 GPa at low temperatures and a suspected metallization occurs at 23 GPa. Moreover, this novel selenium hydride behavior under high pressure and sulfhydryl system having superconductivity is similar, but the latter is much lower than the synthesis pressure. Combining with the theoretical prediction, the hydrogen selenide system is likely to achieve superconducting transitions at lower pressures. The synthesis of new hydrides of selenium is of great significance for studying the superconductivity of hydrogen selenide systems.
