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…
Phonon-phonon interactions in the polarizarion dependence of Raman scattering
Nimrod Benshalom, Maor Asher, Rémy Jouclas +6
We have found that the polarization dependence of Raman scattering in organic crystals at finite temperatures can only be described by a fourth-rank formalism. This generalization…
