  Two-dimensional electron gases(2DEGs)based on KTaO3 are emerging as a
promising platform for spin-orbitronics due to their high Rashba spin-orbit
coupling (SOC) and gate-voltage tunability. The recent discovery of a
superconducting state in KTaO3 2DEGs now expands their potential towards
topological superconductivity. Although the band structure of KTaO3 surfaces of
various crystallographic orientations has already been mapped using
angle-resolved photoemission spectroscopy(ARPES), this is not the case for
superconducting KTaO3 2DEGs. Here, we reveal the electronic structure of
superconducting 2DEGs based on KTaO3 (111) single crystals through ARPES
measurements. We fit the data with a tight-binding model and compute the
associated spin textures to bring insight into the SOC-driven physics of this
fascinating system.
