WebScientific Achievement Two-dimensional superconductivity was discovered at selected interfaces between (111) oriented KTaO 3 and EuO or LaAlO 3 insulating overlayers. Spontaneous in-plane transport anisotropy suggests the emergence of a new “ stripe” phase. Significance and Impact 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.
