Superconducting Interfaces Between Insulating Oxides
This work reports on superconductivity in the electron gas formed at the interface between two insulating dielectric perovskite oxides, LaAlO3 and SrTiO3.
Tunable Rashba spin-orbit interaction at oxide interfaces.
A new example of an electronic property arising from the interfacial breaking of inversion symmetry, namely, a large Rashba spin-orbit interaction, whose magnitude can be modulated by the application of an external electric field is laid out.
Electric field control of the LaAlO3/SrTiO3 interface ground state
The electrostatic tuning of the carrier density allows an on/off switching of superconductivity and drives a quantum phase transition between a two-dimensional superconducting state and an insulating state, which opens the way to the development of new mesoscopicsuperconducting circuits.
Rashba induced magnetoconductance oscillations in the LaAlO 3 -SrTiO 3 heterostructure
We report measurements of the normal state in-plane magnetoconductance in gated LaAlO$_3$-SrTiO$_3$ samples. As the orientation of the magnetic field changes within the plane of the interface, the
Two-dimensional quantum oscillations of the conductance at LaAlO3/SrTiO3 interfaces.
This observation directly indicates the formation of a two-dimensional electron gas originating from quantum confinement at the interface of LaAlO3 /SrTiO3 interfaces characterized by mobilities of the order of several thousands cm2/V s.
Spatially resolved ultrafast magnetic dynamics initiated at a complex oxide heterointerface.
By exciting large-amplitude infrared-active vibrations in a LaAlO3 substrate the authors induce magnetic order melting in a NdNiO3 film across a heterointerface, and observe a magnetic melt front that propagates from the substrate interface into the film, at a speed that suggests electronically driven motion.
Influence of the growth conditions on the LaAIO3/SrTiO3 interface electronic properties
The effects of oxygen pressure during the growth of LaAlO3 on (001) SrTiO3, and of post-deposition annealing were investigated. While little influence on the structure was observed, the transport
Epitaxial growth and thermodynamic stability of SrIrO3/SrTiO3 heterostructures
Obtaining high-quality thin films of 5d transition metal oxides is essential to explore the exotic semimetallic and topological phases predicted to arise from the combination of strong electron
Side Gate Tunable Josephson Junctions at the LaAlO3/SrTiO3 Interface
A superconducting quantum interference device in which the critical currents of each of the constriction-type Josephson junctions can be controlled independently via the side gates is realized.
Ultrafast strain engineering in complex oxide heterostructures.
Vibrational excitation, extended here to a wide class of heterostructures and interfaces, may be conducive to new strategies for electronic phase control at THz repetition rates.
