Kinetically Arrested Twin-Domain State in Formamidinium Lead Iodide
Xia Liang, Milos Dubajic, Zezhu Zeng +4
Hybrid lead halide perovskites exhibit a delicate interplay between average crystallographic symmetry, local structural disorder and A-site orientational dynamics, giving rise to u…
Phase Stability and Transformations in Lead Mixed Halide Perovskites from Machine Learning Force Fields
Xia Liang, Johan Klarbring, Aron Walsh
Lead halide perovskites (APbX) offer tunable optoelectronic properties but feature an intricate phase-stability landscape. Here we employ on-the-fly data collection and an equi…
Thermal transport of amorphous hafnia across the glass transition
Zezhu Zeng, Xia Liang, Zheyong Fan +3
Heat transport in glasses across a wide range of temperature is vital for applications in gate dielectrics and heat insulator. However, it remains poorly understood due to the chal…
Picosecond lifetimes of hydrogen bonds in the halide perovskite CHNHPbBr
Alejandro Garrote-Márquez, Lucas Lodeiro, Norge Cruz Hernández +3
The structures and properties of organic-inorganic perovskites are influenced by the hydrogen bonding between the organic cations and the inorganic octahedral networks. This study…
Dynamic Nanodomains Dictate Macroscopic Properties in Lead Halide Perovskites
Milos Dubajic, James R. Neilson, Johan Klarbring +26
Empirical A-site cation substitution has advanced the stability and efficiency of hybrid organic-inorganic lead halide perovskites solar cells and the functionality of X-ray detect…
