Abstract:
Recent developments in thin-film-fabrication
techniques have enabled the deposition of newly
designed and well controlled oxide interfaces.
These interfaces can have properties which are
significantly different from their constituent
materials. An electronic reconstruction occurring
at the interfaces may be at the origin of these
phenomena. Correlated electrons in oxide
interfaces result in a variety of properties, such as
metal-insulator transition, superconductivity and
magnetism. In my talk I will present quantum
oscillations data and their correlation to the
superconducting dome in the SrTiO3/LaAlO3
system, then I will describe our new methods of
fabricating ballistic quantum wires from oxide
interfaces. The quantum wires exhibit quantized
conductance with long ballistic path and lifted
spin degeneracy.
