Most studies of strong light-matter coupling have been performed in cavities containing traditional inorganic semiconductors such as GaAs , CdTe , ZnO and GaN . Most of these group III-V semiconductors, experience low exciton binding energies in their bulk form and hence require the formation of sophisticated quantum well structures and cryogenic temperatures to sustain excitons and undergo strong-light matter coupling . As an alternative to these materials, recent interest has turned to two-dimensional (2D) hybrid organic-inorganic metal halide phases, which form self-assembled quantum well structures hosting confined excitons. 2D perovskites are promising candidates for polariton condensation due to their ease of thin film growth, high exciton binding energies (~400 meV ), high oscillator strengths , and tunable bandgap . However, despite these advantageous characteristics, reports of room-temperature polariton condensation in 2D perovskites remain elusive, with only one report at low temperatures existing in the literature .
