Definition of superconductivity

: a complete disappearance of electrical resistance in a substance especially at very low temperatures

Examples of superconductivity in a Sentence

Recent Examples on the Web Both groups built devices known as Josephson junctions, in which two superconductors flank a thin layer of nonsuperconducting material, creating a valve for controlling the flow of superconductivity. Charlie Wood, Science | AAAS, "Twisted graphene could power a new generation of superconducting electronics," 19 Nov. 2020 After years of relative stagnation, superconductivity has gotten very exciting again. John Timmer, Ars Technica, "First room-temperature superconductor reported," 14 Oct. 2020 In 1968, Neil Ashcroft, a theorist at Cornell University, had suggested a different type of material should display BCS superconductivity above room temperature: hydrogen under intense pressure. Robert F. Service, Science | AAAS, "After decades, room temperature superconductivity achieved," 14 Oct. 2020 That’s more than 50 degrees hotter than the previous high-temperature superconductivity record set last year. Quanta Magazine, "Room-Temperature Superconductivity Achieved for the First Time," 14 Oct. 2020 To review, hydrogen atoms yield high-frequency phonons, which encourage electron pairs, which enable superconductivity. John Timmer, Ars Technica, "First room-temperature superconductor reported," 14 Oct. 2020 In this way, researchers have produced superconductivity at temperatures tens of degrees above the frigid extremes usually needed. Quanta Magazine, "Alchemy Arrives in a Burst of Light," 30 Sep. 2020 Physicists want to understand this collective behavior because of the potential link to exotic properties such as superconductivity, in which electricity can flow without any resistance. Quanta Magazine, "Elusive Higgs-Like State Created in Exotic Materials," 28 Feb. 2018 Now, scientists have observed one more incredible property: superconductivity.
