## Description

- description: We report  experimental evidence of two fundamental biexciton complexes
    in insulated monolayer WSe2, namely the four-particle neutral biexciton and the
    five-particle negatively charged biexciton. We distinguish these states by power-dependent
    photoluminescence, and we demonstrate full switching between these two states
    by electrical control. We determine the original band states of the elementary
    particles comprising the biexcitons through magneto-optical spectroscopy. We also
    resolve a fine-structure splitting of 2.5 meV for the neutral biexciton emission,
    providing an essential reference for subsequent studies. Our results unveil the
    nature of the multi-particle exciton complexes in TMDs and offer direct routes
    to their deterministic control in many-body quantum phenomena.
