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…
The tetragonal phase of CHNHPbI is strongly anharmonic
Rituraj Sharma, Zhenbang Dai, Lingyuan Gao +7
Halide perovskite (HP) semiconductors exhibit unique strong coupling between the electronic and structural dynamics. The high-temperature cubic phase of HPs is known to be entropic…
Halide perovskites under polarized light: Vibrational symmetry analysis using polarized Raman
Rituraj Sharma, Matan Menahem, Zhenbang Dai +9
In the last decade, hybrid organic-inorganic halide perovskites have emerged as a new type of semiconductor for photovoltaics and other optoelectronic applications. Unlike standard…
Anharmonic Lattice Vibrations in Small-Molecule Organic Semiconductors
Maor Asher, Daniel Angerer, Roman Korobko +3
The intermolecular lattice vibrations in small-molecule organic semiconductors have a strong impact on their functional properties. Existing models treat the lattice vibrations wit…
Anharmonic Host Lattice Dynamics Enable Fast Ion Conduction in Superionic AgI
Thomas M. Brenner, Christian Gehrmann, Roman Korobko +3
Basic understanding of the driving forces of ion conduction in solids is critical to the development of new solid-state ion conductors. Physical understanding of ion conduction is…
Liquid-like Free Carrier Solvation and Band Edge Luminescence in Lead-Halide Perovskites
Yinsheng Guo, Omer Yaffe, Trevor D. Hull +3
We report a strongly temperature dependent luminescence Stokes shift in the electronic spectra of both hybrid and inorganic lead-bromide perovskite single crystals. This behavior s…
