Role of Exciton Binding Energy on LO Phonon Broadening and Polaron Formation in (BA)<sub>2</sub>PbI<sub>4</sub> Ruddlesden–Popper Films Open
The effect of carrier–carrier and carrier–phonon interactions is presented in n = 1 (2D) (BA)2PbI4 Ruddlesden–Popper thin films, and their effect is compared to that of conventional MAPbI3. While temperatur…

Time-Resolved Electrical Scanning Probe Microscopy of Layered Perovskites Reveals Spatial Variations in Photoinduced Ionic and Electronic Carrier Motion Open
We study light-induced dynamics in thin films comprising Ruddlesden-Popper phases of the layered 2D perovskite (C4H9NH3)2PbI4. We probe ionic and electronic carrier dynamics using two …

Direct Observation and Quantitative Analysis of Mobile Frenkel Defects in Metal Halide Perovskites Using Scanning Kelvin Probe Microscopy Open
Ion migration is seen as a primary stability concern of halide perovskite-based photovoltaic and optoelectronic devices. Here, we provide experimental studies of long-distance, reversible ion migration in methylammonium lead iodide (MAPbI3…

Interplay of Mobile Ions and Injected Carriers Creates Recombination Centers in Metal Halide Perovskites under Bias Open
We study the interaction of mobile ions and electronic charges to form nonradiative defects during electric biasing of methylammonium lead triiodide (MAPbI3) and formamidinium lead triiodide (FAPbI3) thin films. Using multimodal microscopy…
