Methodology for Topological Interface Engineering in 2D Photonic Crystals
Ondřej Novák, Martin Veis, Gervasi Herranz
Topological photonics provides a robust and flexible platform for controlling light, enabling functionalities such as backscattering-immune edge transport and slow-light propagatio…
Obstructed Atomic Limit Topological Protection in C4-Symmetric Photonic Crystals for Optical Communications
Ondřej Novák, Martin Veis, Gervasi Herranz
Recent developments in photonic topological phases have revealed that protected edge modes can emerge not only from global topological invariants, but also from symmetry-enforced p…
Stoichiometric control of electron mobility and 2D superconductivity at LaAlO-SrTiO interfaces
Gyanendra Singh, Roger Guzman, Guilhem Saïz +9
SrTiO-based conducting interfaces, which exhibit coexistence of gate-tunable 2D superconductivity and strong Rashba spin-orbit coupling (RSOC), are candidates to host topologic…
Dynamical response and confinement of the electrons at the LaAlO3/SrTiO3 interface
A. Dubroka, M. Roessle, K. W. Kim +10
With infrared ellipsometry and transport measurements we investigated the electrons at the interface between LaAlO3 and SrTiO3. We obtained a sheet carrier density of Ns~5-9x 10E13…
Electron energy loss spectroscopy determination of Ti oxidation state at the (001) LaAlO3/SrTiO3 interface as a function of LaAlO3 growth conditions
Jean-Luc Maurice, Gervasi Herranz, Christian Colliex +10
At the (001) interface between the two band-insulators LaAlO3 and SrTiO3, a high-mobility electron gas may appear, which has been the object of numerous works over the last four ye…
Tunnel magnetoresistance and robust room temperature exchange bias with multiferroic BiFeO3 epitaxial thin films
H. Bea, M. Bibes, S. Cherifi +8
We report on the functionalization of multiferroic BiFeO3 epitaxial films for spintronics. A first example is provided by the use of ultrathin layers of BiFeO3 as tunnel barriers i…
