Effect of high oxygen pressure annealing on superconducting Nd1.85Ce0.15CuO4 thin films by pulsed laser deposition from Cu-enriched targets
We show that the quality of Nd1.85Ce0.15CuO4 films grown by pulsed laser
deposition can be enhanced by using a non-stoichiometric target with extra
copper added to suppress the formation of a parasitic (Nd, Ce)2O3 phase. The
properties of these films are less dependent on the exact annealing procedure
after deposition as compared to films grown from a stoichiometric target. Film
growth can be followed by a 1 bar oxygen annealing, after an initial vacuum
annealing, while retaining the superconducting properties and quality. This
enables the integration of electron-doped cuprates with their hole-doped
counterparts on a single chip, to create, for example, superconducting
pn-junctions.Comment: This is an author-created, un-copyedited version of an article

Epistemic Quantified Boolean Logic
This paper is aimed as a contribution to the use of formal modal languages in Artificial Intelligence. We introduce a multi-modal version of Second-order Propositional Modal Logic (SOPML), an extension of modal logic with propositional quantification, and illustrate its usefulness as a specification language for knowledge representation as well as temporal and spatial reasoning. Then, we define novel notions of (bi)simulation and prove that these preserve the interpretation of SOPML formulas. Finally, we apply these results to assess the expressive power of SOPML
Strain accommodation through facet matching in LaSrCuO/NdCeCuO ramp-edge junctions
Scanning nano-focused X-ray diffraction (nXRD) and high-angle annular
dark-field scanning transmission electron microscopy (HAADF-STEM) are used to
investigate the crystal structure of ramp-edge junctions between
superconducting electron-doped NdCeCuO
and superconducting hole-doped LaSrCuO
thin films, the latter being the top layer. On the ramp, a new growth mode of
LaSrCuO with a 3.3 degree tilt of the
c-axis is found. We explain the tilt by developing a strain accommodation model
that relies on facet matching, dictated by the ramp angle, indicating that a
coherent domain boundary is formed at the interface. The possible implications
of this growth mode for the creation of artificial domains in morphotropic
materials are discussed.Comment: 5 pages, 4 figures & 3 pages supplemental information with 2 figures.
