| Outline of Final Research Achievements |
The purpose of this study is to achieve the polariton laser at room temperature using the micro-cavity containing organic-inorganic hybrid perovskite materials which have extremely large exciton binding energies. We have measured the strong exciton-cavity coupling with a large vacuum Rabi splitting of 146 meV. However, we have not achieved an establishment of the polariton laser. We are now improving the cavity structure to achieve the polariton laser.
We have also studied the excitonic properties of three-dimensional hybrid perovskite materials. We have confirmed that the excitons exist even at room temperature, and succeeded in the estimation of the exciton binding energy to be 20 ~ 40 meV.
