Query: Inhomogeneous superconductivity and quasilinear magnetoresistance at
  amorphous LaTiO3/SrTiO3 interfaces   We have studied the transport properties of LaTiO3/SrTiO3 (LTO/STO)
heterostructures. In spite of 2D growth observed in reflection high energy
electron diffraction, Transmission Electron Microscopy images revealed that the
samples tend to amorphize. Still, we observe that the structures are
conducting, and some of them exhibit high conductance and/or superconductivity.
We established that conductivity arises mainly on the STO side of the
interface, and shows all the signs of the 2-dimensional electron gas usually
observed at interfaces between SrTiO3 and LaTiO3 or LaAlO3, including the
presence of two electron bands and tunability with a gate voltage. Analysis of
magnetoresistance (MR) and superconductivity indicates presence of a spatial
fluctuations of the electronic properties in our samples. That can explain the
observed quasilinear out-of-plane MR, as well as various features of the
in-plane MR and the observed superconductivity.
