WebAug 19, 2024 · Recently, two-dimensional superconductivity was discovered at the oxide interface between KTaO 3 and LaAlO 3 (or EuO), whose superconducting transition temperature T c is up to 2.2 K and exhibits strong crystalline-orientation dependence. However, the origin of the interfacial electron gas, which becomes superconducting at low … WebHere we report on the discovery of superconductivity in electron gases formed at interfaces between (111)-oriented KTaO3 and insulating overlayers of either EuO or LaAlO3. The superconducting transition temperature, as high as 2.2 kelvin, is about one order of magnitude higher than that of the LaAlO3/SrTiO3 system.
