Overview

Observational analysis reveals that twist-angle engineering affects exciton g-factors and electric dipole moments in heterostructures, implying potential for quantum materials design.

Key Points

  • The twist angle in MoS2/WS2 heterobilayers shapes exciton g-factors and electric dipole moments, enhancing their quantum properties.
  • A discrete g-factor with opposite-sign Zeeman responses is observed, indicating the role of local stacking in electronic properties.
  • The moiré superlattice structure maintains monolayer spin-valley locking, which impacts the electronic and magnetic behavior.
  • These findings suggest the potential for customized quantum materials through precise twist-angle manipulation.
