摘要

Since 2014,when the research group of Professor Tian Cui (Jilin University) predicted [1] (and experiments [2] confirmed) the existence of an unusual high-pressure compound,H3S,with superconductivity at 191-204 K,a new era in studies of superconductivity began.In 2019,a new record of high-temperature superconductivity was set,with LaH10 experimentally proven to be a superconductor with a nearly room-Tc of 250-260 K [3,4].H3S and LaH10 cannot be used in practical applications,because they exist only at megabar pressures,but their study may hint at which compounds can be room-temperature superconductors at normal pressure.
