Phase Segregation Dynamics in Mixed-Halide Perovskites Revealed by Plunge-Freeze Cryogenic Electron Microscopy
Qingyuan Fan, Yi Cui, Yanbin Li +7
Mixed-halide lead perovskites, with photoexcited charge-carrier properties suitable for high-efficiency photovoltaics, hold significant promise for high-efficiency tandem solar cel…
The nature of dynamic local order in CHNHPbI and CHNHPbBr
Nicholas Weadock, Tyler Sterling, Julian Vigil +12
Hybrid lead halide perovskites (LHPs) are a class of semiconductor with novel properties that are distinctively governed by structural fluctuations. Diffraction experiments sensiti…
Cesium-involved electron transfer and electron-electron interaction in high-pressure metallic CsPbI3
Feng Ke, Jiejuan Yan, Shanyuan Niu +8
Electron-phonon coupling was believed to govern the carrier transport in halide perovskites and related phases. Here we demonstrate that electron-electron interaction plays a direc…
Visualization of Dynamic Polaronic Strain Fields in Hybrid Lead Halide Perovskites
B. Guzelturk, T. Winkler, T. Van de Goor +14
Excitation localization involving dynamic nanoscale distortions is a central aspect of photocatalysis, quantum materials and molecular optoelectronics. Experimental characterizatio…
On the question of dynamic domains and critical scattering in cubic methylammonium lead triiodide
Nicholas J. Weadock, Peter M. Gehring, Aryeh Gold-Parker +3
We investigate the hypothesis of dynamic tetragonal domains occuring in cubic CHNHPbI using high-resolution neutron spectroscopy to study a fully deuterated single crys…
Acoustic Phonon Lifetimes Limit Thermal Transport in Methylammonium Lead Iodide
Aryeh Gold-Parker, Peter M. Gehring, Jonathan M. Skelton +6
Hybrid organic-inorganic perovskites (HOIPs) have become an important class of semiconductors for solar cells and other optoelectronic applications. Electron-phonon coupling plays…
