## Description

- description: Two-dimensional (2D) transition metal dichalcogenides (TMDs) are a
    versatile class of quantum materials of interest to various fields including,
    e.g., nanoelectronics, optical devices, and topological and correlated quantum
    matter. Tailoring the electronic properties of TMDs is essential to their applications
    in many directions. Here we report that a highly controllable and uniform on-chip
    2D metallization process converts a class of atomically thin TMDs into robust
    superconductors, a property belonging to none of the starting materials. As examples,
    we demonstrate the introduction of superconductivity into a class of 2D air-sensitive
    topological TMDs, including monolayers of Td-WTe2, 1T’-MoTe2 and 2H-MoTe2, as
    well as their natural and twisted bilayers, metalized with an ultrathin layer
    of Palladium. This class of TMDs are known to exhibit intriguing topological phases
    ranging from topological insulator, Weyl semimetal to fractional Chern insulator.
    The unique, high quality two-dimensional metallization process is based on our
    recent finding of the long-distance non-Fickian in-plane mass transport and chemistry
    in 2D that occur at surprisingly low temperatures and in devices fully encapsulated
    with inert insulating layers. Highly compatible with existing nanofabrication
    techniques for van der Waals (vdW) stacks, our results offer a route to designing
    and engineering superconductivity and topological phases in a class of correlated
    2D materials.
