## Description

- description: Energy transfer is a ubiquitous phenomenon that delivers energy from
    a blue-shifted emitter to a red-shifted absorber, which has enabled plentiful
    photonic applications of light-emitting diodes (LEDs), lasers, solar cells, and
    display devices1-5. The fast-emerging two-dimensional (2D) semiconductors offer
    unique opportunities for exploring new energy transfer mechanism in the atomic-scale
    limit enabled by confined geometry and van der Waals architectures, which transcend
    the conventional Förster and Dexter types. Herein, we have successfully designed
    and constructed a planar optical microcavity-confined MoS2/hBN/WS2 heterojunction,
    which realizes the strong coupling among donor exciton, acceptor exciton and cavity
    photon mode for the first time. Such a configuration demonstrates the unconventional
    energy transfer via ultrafast polariton relaxation, leading to the brightening
    of MoS2 neutral exciton with a record-high enhancement factor of ~440, i.e., two-order-of-magnitude
    higher than the data reported to date. A short characteristic time of ~1.3 ps
    is extracted by setting up a high-resolution k-space transient-reflectivity spectroscopy.
    This ultrafast polariton relaxation is attributed to the significantly enhanced
    intra- and inter-branch exciton-exciton scattering to overcome the hot phonon
    bottleneck effect, as revealed by theoretical calculation with the coupled rate
    equations. Our study not only opens a new direction of microcavity 2D semiconductor
    heterojunctions for high-brightness ultrafast polaritonic light sources, but also
    provides a new paradigm to study the ultrafast polariton carrier dynamics.
