Recently, the reporter learned from the Chinese Academy of Sciences, Hefei Institute of Material Science, Institute of Solid State Physics and Strong Magnetic Field Science Center joint research team under the conditions of ultrahigh pressure for the first time in a new material - molybdenum disulfide observed superconductivity. Relevant research results have been selected for editing recommended articles, recently published in the international physics top journals "Physical Review Letters" on.
Researchers in the self-built high-pressure integrated test platform, the use of diamond on the top anvil produced by the high pressure conditions, low temperature electrical transport measurements found: molybdenum disulfide 90GPa (900000 atmospheric pressure) under the conditions of pressure into a superconductor, Within the pressure range of 130-220 GPa (near the pressure of the Earth's outer core), the critical temperature of superconducting transition can be as high as 12K and the microscopic mechanism of superconductivity is explained by density functional theory calculations.
