| Outline of Final Research Achievements |
In this study, we comprehensively investigated the photon-exciton interaction in a microcavity using an organic semiconductor materials and their coherent emission phenomenon. As materials, organic crystals having a strong molecular orientation and lead halide perovskite crystals were mainly used. We have succeeded in producing a microcavity using these materials with a high quality factors. Furthermore, by measuring the angle-resolved emission characteristics and the time-resolved emission characteristics, the coupling strength between the photon and exciton modes in the cavity systems and the relaxation mechanism of the excited species to the polariton state were clarified. These results were based on the international collaborations.
