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

Not Accessible

Abstract

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.
