Collective photon emission and ferroelectric exciton ordering near Mott insulating state in WSe2/WS2 heterobilayers

Key Points

• Collective photon emission occurs as excitons order in a heterobilayer structure.
• Key evidence includes measurements showing significant exciton alignment in WSe2/WS2 layers.
• Observational analysis combines optical measurements and theoretical interpretations of Mott insulating behavior.
• This work may enable future developments in materials for electronic and photonic applications.
