## Description

- description: Ruddlesden-Popper perovskites are natural two-dimensional (2D) semicon-
    ductors composed of nanometer-thin inorganic layers separated by organic bar-
    riers. Combining the optical quality of inorganic quantum-wells with the flexibility
    of organic crystals, they emerged as promising platforms for nanotechnology across
    the fields of photovoltaics, optoelectronics, and photonics. However, it has remained
    exceptionally difficult to electrically control their optical response, which
    is dominated by neutral excitons, due to persistent challenges to introduce doping.
    Here, we demonstrate bipolar, continuous tuning of light emission and absorption
    in 2D perovskites by elec- trically injecting carriers to densities as high as
    10^12 cm−2. Our approach is based on interfacing ultrathin sheets of perovskites
    with few-layer graphene and hexagonal boron nitride into gate-tunable heterostructures.
    We reveal the emergence of both negatively- and positively-charged excitons, or
    trions, with binding energies up to 46 meV, arguably the highest ones measured
    for 2D systems. Trions are shown to dominate light emission and propagate with
    mobilities reaching 200cm2/(Vs) at elevated temperatures. Our findings introduce
    the physics of interacting mixtures of optical and electrical excitations to the
    broad family of inorganic-organic nanostructures. The presented strategy to electrically
    control the optical response of 2D perovskites opens up promising avenues towards
    electrically-modulated light-emitters, externally guided charged exciton currents,
    and exciton transistors based on layered, hybrid semiconductors.
