Perovskites have benefitted from a recent surge in research due to their surprising properties, especially within the context of their relatively easy production. Much of this research has focused on understanding the reason for their surprisingly efficient photovoltaic properties, but I will instead focus on the fundamentals of the light-matter interaction within the material. This will include the presentation of ultrafast time-resolved lasing measurements of perovskite nanowires.
This talk will contain relevant information about why perovskites are a current research interest, as well as background information about exciton-polaritons in traditional semiconductors. In addition, experimental details and results from ultrafast time-resolved polariton lasing will be presented. This data will provide important insight into general polariton dynamics, including the ‘condensation’ of polaritons, and perhaps even about the bare excitons in the nanowire as well.
