Patterning of superconducting two-dimensional electron gases based on AlO/KTaO(111) interfaces
Hugo Witt, Srijani Mallik, Luis M. Vicente-Arche +7
The versatility of properties displayed by two-dimensional electron gases (2DEGs) at oxide interfaces has fostered intense research in hope of achieving exotic electromagnetic effe…
Direct visualization of Rashba-split bands and spin/orbital-charge interconversion at KTaO interfaces
Sara Varotto, Annika Johansson, Börge Göbel +10
Rashba interfaces have emerged as promising platforms for spin-charge interconversion through the direct and inverse Edelstein effects. Notably, oxide-based two-dimensional electro…
Superfluid stiffness of a KTaO3-based two-dimensional electron gas
S. Mallik, G. Ménard, G. Saïz +6
After almost twenty years of intense work on the celebrated LaAlO3/SrTiO3 system, the recent discovery of a superconducting two-dimensional electron gases (2-DEG) in (111)-oriented…
