摘要

我们使用时间分辨光电发射电子显微镜来研究杂化有机钙钛矿薄膜。我们观察到异质阱态密度在纳米尺度上的变化。进一步，我们研究了这些纳米尺度区域内的光激发载流子动力学。

Investigation of Trap States and Their Dynamics in Hybrid Organic-inorganic Mixed Cation Perovskite Films Using Time Resolved Photoemission Electron Microscopy

We use time-resolved photoemission electron microscopy to investigate hybrid organic perovskite thin films. We observe heterogeneous trap state densities varying on the nanometer scale. Further, we study the photo-excited carrier dynamics within these nanoscale regions.
