## Description

- description: Understanding the nature of grain boundaries is a prerequisite for
    fabricating high-performance superconducting bulks and wires. For iron-based superconductors
    [e.g. Ba(Fe,Co) 2As 2, Fe(Se,Te), and NdFeAs(O,F)], the dependence of the critical
    current density Jc on misorientation angle (θGB) has been explored on [001]-tilt
    grain boundaries, but no data for other types of orientations have been reported.
    Here, we report on the structural and transport properties of Fe(Se,Te) grown
    on　CeO 2-buffered symmetric [010]-tilt roof-type SrTiO 3 bicrystal substrates
    by pulsed laser deposition. X-ray diffraction and transmission electron microscopy
    revealed that θGB of Fe(Se,Te) was smaller whereas θGB of CeO 2 was larger than
    that of the substrate. The difference in θGB between the CeO 2 buffer layer and
    the substrate is getting larger with increasing θGB. For θGB≥24∘ of the substrates,
    θGB of Fe(Se,Te) was zero, whereas θGB of CeO 2 was continuously increasing. The
    inclined growth of CeO 2 can be explained by the geometrical coherency model.
    The c-axis growth of Fe(Se,Te) for θGB≥24∘ of the substrates is due to the domain
    matching epitaxy on (221) planes of CeO 2. Electrical transport measurements confirmed
    no reduction of inter-grain Jc for θGB≤9∘, indicative of strong coupling between
    the grains.
