## Description

- description: The recent observations of fractional quantum anomalous Hall effect
    in twisted bilayer molybdenum ditelluride (tMoTe2) has confirmed the existence
    of fractional Chern insulators (FCI) in the absence of magnetic fields. The creation
    of superconductivity (SC) in FCIs can in principle lead to new electronic states
    of matter in unexplored conditions. However, it is challenging to create SC using
    traditional means in such air sensitive two-dimensional (2D) moiré materials.
    Here, we introduce a new strategy for quantum engineering of SC in moiré materials
    based on direct, on-chip, and fully encapsulated 2D growth. We achieve robust
    and designable SC in Pd-metalized tMoTe2 and observe anomalous superconducting
    effects in short and high-quality junctions across ~ 20 moiré cells. The junction
    surprisingly exhibits enhanced, instead of weakened, SC with both a higher critical
    temperature and a higher critical magnetic field compared to its adjacent PdxMoTe2
    superconductor. The critical current further exhibits a striking V-shaped minimum
    at zero magnetic field. All these behaviors are unexpected in conventional Josephson
    junctions and are indeed absent in junctions of natural bilayer MoTe2 created
    using the same approach. We discuss implications of these observations, including
    the possible formation of mixed even- and odd-parity SC pairing at the moiré junctions.
    Our results establish a route to engineering superconducting moiré junctions and
    pave the way for studying SC with fractionalized electrons.
