Magnetic effects at the interface between non-magnetic oxides.
TLDR
The conducting oxide interface now provides a versatile system to induce and manipulate magnetic moments in otherwise non-magnetic materials.
Orbital reconstruction and the two-dimensional electron gas at the LaAlO3/SrTiO3 interface.
TLDR
These results are based on extensive investigations of the electronic properties and of the orbital structure of the interface using x-ray absorption spectroscopy and find that the degeneracy of the Ti 3d states is fully removed and that theTi 3d xy levels become the first available states for conducting electrons.
Electronically coupled complementary interfaces between perovskite band insulators.
TLDR
The successful realization of closely spaced complementary interfaces in SrTiO3-LaAlO3 thin-film multilayer structures is reported, and the high carrier mobilities characterizing the separate conducting interfaces are found to be maintained in coupled structures down to subnanometre interface spacing.
Parallel electron-hole bilayer conductivity from electronic interface reconstruction.
TLDR
Combined theoretical and experimental evidence suggests two spatially separated sheets with electron and hole carriers, that are as close as 1 nm, in the perovskite SrTiO3-LaAlO3 structure.
Superconducting Mg–B films by pulsed-laser deposition in an in situ two-step process using multicomponent targets
Superconducting thin films have been prepared in an insitu two-step process, using the Mg–B plasma generated by pulsed-laser ablation. The target was composed of a mixture of Mg and MgB2 powders to…
Josephson supercurrent through a topological insulator surface state.
TLDR
Direct evidence for Josephson supercurrents in superconductor (Nb)-topological insulator (Bi(2)Te(3))-superconductor electron-beam fabricated junctions is provided by the observation of clear Shapiro steps under microwave irradiation, and a Fraunhofer-type dependence of the critical current on magnetic field.
Multiband model for tunneling in MgB2 junctions
A theoretical model for quasiparticle and Josephson tunneling in multiband superconductors is developed and applied to MgB2-based junctions. The gap functions in different bands in MgB2 are obtained…
Quantum oscillations and subband properties of the two-dimensional electron gas at the LaAlO3/SrTiO3 interface
We have performed high field magnetotransport measurements to investigate the interface electron gas in a high mobility SrTiO3/SrCuO2/LaAlO3/SrTiO3 heterostructure. Shubnikov-de Haas oscillations…
Low carrier concentration crystals of the topological insulator Bi2−xSbxTe3−ySey: a magnetotransport study
In 3D topological insulators achieving a genuine bulk-insulating state is an important research topic. Recently, the material system (Bi,Sb)2(Te,Se)3 (BSTS) has been proposed as a topological…
Structure–Property Relation of SrTiO3/LaAlO3 Interfaces
A large variety of transport properties have been observed at the interface between the insulating oxides SrTiO3 and LaAlO3 such as insulation, 2D interface metallicity, 3D bulk metallicity, magnetic…
