Evidence of Room-Temperature Superconductivity in Carbonaceous Sulfur Hydride
Superconductivity at room temperature has been a long-sought goal of condensed-matter physics. Here we report the discovery of superconductivity in a carbonaceous sulfur hydride system under high pressure. We observe a superconducting transition temperature of 287.7 Kelvin (approximately 15 degrees Celsius) at a pressure of 267 gigapascals, using a diamond-anvil cell. Superconductivity is established by electrical resistance measurements, magnetic susceptibility tests, and Raman spectroscopy. This work opens avenues for room-temperature quantum electronics and energy transmission.
