Intrinsic Negative-U Centers in Freestanding LaAlO3/SrTiO3 Micro-membranes
Giulia Meucci, Pinelopi O. Konstantinopoulou, Thies Jansen +15
The LaAlO3/SrTiO3 (LAO/STO) interface hosts a rich range of electronic phenomena, including unconventional electron pairing that in quantum dots gives rise to a negative effective…
Coexistence of high electron-mobility, unpaired spins, and superconductivity at high carrier density SrTiO-based interfaces
Thor Hvid-Olsen, Christina H. Christoffersen, Damon J. Carrad +6
The band-structure of SrTiO-based two-dimensional electron gasses (2DEGs), have been found to play a role in features such as the superconducting dome, high-mobility t…
Ultra-High Carrier Mobilities in Ferroelectric Domain Wall Corbino Cones at Room Temperature
Conor J. McCluskey, Matthew G. Colbear, James P. V. McConville +12
Recently, electrically conducting heterointerfaces between dissimilar band-insulators (such as lanthanum aluminate and strontium titanate) have attracted considerable research inte…
Oxide spin-orbitronics: spin-charge interconversion and topological spin textures
Felix Trier, Paul Noël, Joo-Von Kim +3
Quantum oxide materials possess a vast range of properties stemming from the interplay between the lattice, charge, spin and orbital degrees of freedom, in which electron correlati…
A switchable two-dimensional electron gas based on ferroelectric Ca:SrTiO
Julien Bréhin, Felix Trier, Luis M. Vicente-Arche +14
Two-dimensional electron gases (2DEGs) can form at the surface of oxides and semiconductors or in carefully designed quantum wells and interfaces. Depending on the shape of the con…
Universality of Electron Mobility in LaAlO/SrTiO and bulk SrTiO
F. Trier, K. V. Reich, D. V. Christensen +5
