Abstract

We investigate how many-electron excited states emerge in twisted MoSe₂ homobilayers when the lattice reconstructions evolve. We identify a new trion resonance in the transition regime of lattice reconstruction. Magnetic-field-dependent measurements, supported by first-principles calculations, indicate that the exciton forms at the K valley while the doped hole resides in the Γ valley. First-principles calculations further indicate that two nearly degenerate exciton resonances can arise, localized at different sites within the moiré supercell.
