## Description

- description: Polymorphic transitions in layered transition metal dichalcogenides
    provide an excellent platform for discovering exotic phenomena associated with
    metastable states, ranging from topological phase transitions to enhanced superconductivity.
    In particular, the transition from 2H to 1T′-MoTe2, which was thought to be induced
    by high-energy photon irradiation among many other means, has been intensely studied
    for its technological relevance in nanoscale transistors. Despite the remarkable
    electrical performance arising from this 2H-to-1T′ transition, it remains controversial
    whether a crystalline 1T′ phase is produced because optical signatures of this
    putative transition are found to be associated with the formation of elemental
    Te clusters instead. Here, we demonstrate the creation of an intrinsic 1T′ lattice
    after irradiating a mono- or few-layer 2H-MoTe2 with a single field-enhanced terahertz
    pulse, whose low photon energy limits possible structural damages by optical pulses.
    To visualize the temporal evolution of this irreversible transition, we further
    develop a single-shot terahertz pump-second harmonic probe technique, and we find
    that the transition out of the 2H phase occurs within 10 ns after photoexcitation.
    Our results not only resolve the long-standing debate over the light-induced polymorphic
    transition in MoTe2, they also highlight the unique capability of strong-field
    terahertz pulses in manipulating the structure of quantum materials.
