## Description

- description: Stark effect is one of the celebrated phenomena in modern physics and
    appealing for applications. While in condensed matter it has prospered only for
    excitons, whether other collective excitations can display Stark effect remains
    elusive. Here, we demonstrate the phonon Stark effect in a two-dimensional quantum
    system of bilayer 2H-MoS2. The longitudinal acoustic phonon red-shifts linearly
    with applied electric fields and can be tuned over ~ 1 THz, evidencing giant Stark
    effect of phonons. Together with many-body ab initio calculations, we uncover
    that the observed phonon Stark effect originates fundamentally from the strong
    coupling between phonons and interlayer excitons (IXs). In addition, IX-mediated
    electro-phonon intensity modulation up to ~ 1200% is discovered for infrared-active
    phonon A2u. Our results unveil the emerging phonon Stark effect and effective
    phonon engineering by IX-mediated mechanism, promising a plethora of many-body
    physics and potential technological innovations.
