    van der Waals heterostructure on exciton and trion emission
  title_type: original

## Description

- description: We study van der Waals heterostructures consisting of monolayer Mo⁢Se2
    and few-layer Cr2⁢Ge2⁢Te6 fully encapsulated in hexagonal boron nitride using
    low-temperature photoluminescence and polar magneto-optical Kerr-effect measurements.
    Photoluminescence characterization reveals a partial quenching and a change of
    the exciton-trion emission ratio in the heterostructure as compared to the isolated
    Mo⁢Se2 monolayer. Under circularly polarized excitation, we find that the exciton-trion
    emission ratio depends on the relative orientation of excitation helicity and
    Cr2⁢Ge2⁢Te6 magnetization, even though the photoluminescence emission itself is
    unpolarized. This observation hints at an ultrafast, spin-dependent interlayer
    charge transfer that competes with exciton and trion formation and recombination.
