## Description

- description: Doped van der Waals heterostructures host layer-hybridized trions,
    i.e. charged excitons with layer-delocalized constituents holding promise for
    highly controllable optoelectronics. Combining a microscopic theory with photoluminescence
    (PL) experiments, we demonstrate the electrical tunabil- ity of the trion energy
    landscape in naturally stacked WSe2 bilayers. We show that an out-of-plane electric
    field modifies the energetic ordering of the lowest lying trion states, which
    consist of layer- hybridized Λ-point electrons and layer-localized K-point holes.
    At small fields, intralayer-like trions yield distinct PL signatures in opposite
    doping regimes characterized by weak Stark shifts in both cases. Above a doping-asymmetric
    critical field, interlayer-like species are energetically favored and produce
    PL peaks with a pronounced Stark red-shift and a counter-intuitively large intensity
    aris- ing from efficient phonon-assisted recombination. Our work presents an important
    step forward in the microscopic understanding of layer-hybridized trions in van
    der Waals heterostructures and paves the way towards optoelectronic applications
    based on electrically controllable atomically-thin semiconductors.
