HIGHLIGHTS
- who: S. Mallik from the (UNIVERSITY) have published the research: Superfluid stiffness of a KTaO3-based two-dimensional electron gas, in the Journal: (JOURNAL) of 18/02/2022
- what: The authors report gate tunable superconductivity in 2-DEGs generated at the surface of a -oriented KTaO3 crystal by the simple sputtering of a thin Al layer. Taking into account the presence of disorder and finite-frequency effect, the authors show that the superconducting transition follows the Berezinskii-Kosterlitz-Thouless model, which was not observed on SrTiO3-based interfaces. data fittedenveloppe +1.9 nm Al Ta . . .
