Recently, the research team led by Alexander F. Goncharov, a researcher at the Institute of Solid State Physics of the Hefei Institute of Physics, Chinese Academy of Sciences, made a breakthrough in the synthesis of high-temperature superconducting materials based on hydrogen sulfide. Related research work was published in the journal Physical Review B (Phys. Rev. B 95, 140101 (2017)) with the topic of stable high-pressure phases in the HS system determined by chemically reacting hydrogen and sulfur.
The discovery of the 200 K superconductivity of the sulphide-hydrogen system is an important event in the field of condensed matter physics in the past year. At present, the theoretical prediction of the high-temperature superconducting phase H3S 
The structure of the H3S phase is the most stable, and its high-temperature superconducting properties originate from this phase, not H2S-H2, confirming theoretically the correctness of the prediction of high-temperature superconducting phase. Their results provide a large number of H3S high temperatures. The optical properties of the superconducting phase, such as structure and characteristic vibrational spectra, ended the debate between theory and experiment regarding the high-temperature superconducting phase.
The study is the second article on sulfur-hydrogen systems published by Alexander F. Goncharov as the first author of Solids. These results are for the understanding of superconducting phases and components, the control of superconductivity in high-temperature and high-pressure synthesis, and the study of superconductivity. The mechanism has very important significance. After joining the Quantum Quantum Center, Alexander F. Goncharov published research papers in the Nature and Science journals and reported on the achievements made by Hefei Institute of Material Sciences in extreme high pressure and high temperature environments. These results have benefited from the establishment of a high-pressure research platform for solid-centered extreme-quantum-substance-centered systems, particularly the successful implementation of high-pressure hydrogen loading.
The above research was supported by the National Natural Science Foundation's "Exploration of Novel Chemical State under Extreme Conditions" project.
