Sub-diffraction Imaging of Carrier Dynamics in Halide Perovskite Semiconductors: Effects of Passivation, Morphology, and Ion Motion

Madeleine D. Breshears, Justin Pothoof, Rajiv Giridharagopal +1

We spatially resolve photocarrier dynamics in halide perovskites using time-resolved electrostatic force microscopy (trEFM) to map surface potential equilibration during photoexcit…

Surface Passivation Suppresses Local Ion Motion in Halide Perovskites

Justin Pothoof, Robert J. E. Westbrook, Rajiv Giridharagopal +2

We use scanning probe microscopy to study ion migration in the formamidinium (FA)-containing halide perovskite semiconductor in the pres…
