Scandium's electrons may explain predicted room-temperature superconductivity
Scientists have confirmed the existence of a predicted room temperature superconductor, while explaining the microscopic mechanism that distinguishes it from a similar one discovered several years ago. The work, published in the journal Physical Review B, offers "a theoretical blueprint for the future design of superior superconductor hydrides" the physicists write.
Scientists have discovered a predicted room-temperature superconductor, with a theoretical explanation for its enhanced properties compared to a similar material. The research, published in Physical Review B, identifies the role of scandium atoms in modifying the critical temperature of the superconducting material LaSc2H24. The material's electronic band structure is anisotropic, meaning it has two different superconductivity channels with varying critical temperatures.
Scandium's 3d electrons interact strongly with hydrogen ions in the material, reshaping the Fermi surface and reducing differences between the superconducting gaps. This discovery provides a blueprint for designing superior superconductor hydrides, potentially paving the way for room-temperature superconductivity.
