Coherent Spin Dynamics of Electrons in Two-Dimensional (PEA)PbI Perovskites
Erik Kirstein, Evgeny A. Zhukov, Dmitri R. Yakovlev +6
The versatile potential of lead halide perovskites and two-dimensional materials is merged in the Ruddlesen-Popper perovskites having outstanding optical properties. Here, the cohe…
Persistent Enhancement of Exciton Diffusivity in CsPbBr3 Nanocrystal Solids
Wenbi Shcherbakov-Wu, Seryio Saris, Thomas Sheehan +6
In semiconductors, exciton or charge carrier diffusivity is typically described as an inherent material property. Here, we show that the transport of excitons (i.e., bound electron…
Direct observation of ultrafast lattice distortions during exciton-polaron formation in lead-halide perovskite nanocrystals
Hélène Seiler, Daniela Zahn, Victoria C. A. Taylor +4
The microscopic origin of slow carrier cooling in lead-halide perovskites remains debated, and has direct implications for applications. Slow carrier cooling has been attributed to…
Phonon-Mediated Attractive Interactions between Excitons in Lead-Halide-Perovskites
Nuri Yazdani, Maryna I. Bodnarchuk, Federica Bertolotti +20
Understanding the origin of electron-phonon coupling in lead-halide perovskites (LHP) is key to interpreting and leveraging their optical and electronic properties. Here we perform…
