Noncollinear electric dipoles in a polar, chiral phase of CsSnBr perovskite
Douglas H. Fabini, Kedar Honasoge, Adi Cohen +12
Polar and chiral crystal symmetries confer a variety of potentially useful functionalities upon solids by coupling otherwise noninteracting mechanical, electronic, optical, and mag…
Disentangling the Effects of Structure and Lone-Pair Electrons in the Lattice Dynamics of Halide Perovskites
Sebastián Caicedo-Dávila, Adi Cohen, Silvia G. Motti +8
Metal halide perovskites have shown great performance as solar energy materials, but their outstanding optoelectronic properties are paired with unusually strong anharmonic effects…
Anharmonic Fluctuations Govern the Band Gap of Halide Perovskites
Stefan A. Seidl, Xiangzhou Zhu, Guy Reuveni +5
We determine the impact of anharmonic thermal vibrations on the fundamental band gap of CsPbBr, a prototypical model system for the broader class of halide perovskite semicondu…
Static and Dynamic Disorder in Formamidinium Lead Bromide Single Crystals
Guy Reuveni, Yael Diskin-Posner, Christian Gehrmann +8
We show that formamidinium lead bromide is unique among the halide perovskite crystals because its inorganic sub-lattice exhibits intrinsic local static disorder that co-exists wit…
The Disorder Origin of Raman Scattering In Perovskites Single Crystals
Matan Menahem, Nimrod Benshalom, Maor Asher +5
The anharmonic lattice dynamics of oxide and halide perovskites play a crucial role in their mechanical and optical properties. Raman spectroscopy is one of the key methods used to…
Dynamic disorder in Bi sub-lattice of -BiO
Rituraj Sharma, Nimrod Benshalom, Maor Asher +4
-BiO is one of the fastest known solid oxide ion conductors owing to its intrinsically defective fluorite-like structure with 25\% vacant sites in the O sub-lattice. Num…
