## Description

- description: 'Van der Waals heterostructures made of high temperature cuprate superconductors
    hold high tech- nological promise. One of the obstackles hindering the progress
    is the detrimental effect of disorder on the characteristics of the Josephson
    junctions realized by the van der Waals heterostructures. Here we report the fabrication
    of twisted high-temperature superconducting Bi2Sr2CuCa2O8+δvan der Waals heterostructures
    that can achieve characteristics, in particular, critical current up to 1.2kA/cm2,
    similar to those of the intrinsic Josephson junctions in bulk crystals. We use
    a cryo- genic stacking technique and a solvent-free stencil mask method while
    additionally covering the interface with the insulating hBN crystals. Despite
    the high-vacuum condition down to 10−6 mbar in the evaporation chamber, the interface
    appears to be protected from water molecules during the in-situ metal deposition
    only if it is fully encapsulated. We perform their direct comparison with the
    not encapsulated interface and reveal that the encapsulated interfaces show the
    main features of the coherent Josephson junctions such as: (i) a critical current
    comparable to the one of the intrin- sic Josephson junctions; (ii) non-monotonic
    temperature dependence of the critical current; (iii) the bulk value of the superconducting
    transition temperature. In addition, we find that heterostructures fabricated
    in this way are more stable in time.'
