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…
Anharmonic Lattice Dynamics in Sodium Ion Conductors
Thomas M. Brenner, Manuel Grumet, Paul Till +4
We employ THz-range temperature-dependent Raman spectroscopy and first-principles lattice-dynamical calculations to show that the undoped sodium ion conductors NaPS and iso…
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 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…
Homogenization of Halide Distribution and Carrier Dynamics in Alloyed Organic-Inorganic Perovskites
Juan-Pablo Correa-Baena, Yanqi Luo, Thomas M. Brenner +15
Perovskite solar cells have shown remarkable efficiencies beyond 22%, through organic and inorganic cation alloying. However, the role of alkali-metal cations is not well-understoo…
Temperature-dependent Hysteresis in MAPbI3 Solar Cells
Igal Levine, Pabitra K. Nayak, Jacob Tse-Wei Wang +7
Hysteresis in the current-voltage characteristics of hybrid organic-inorganic perovskite-based solar cells is one of the fundamental aspects of these cells that we do not understan…
Are Mobilities in Hybrid Organic-Inorganic Halide Perovskites Actually 'High'?
Thomas M. Brenner, David A. Egger, Andrew M. Rappe +3
We present an experimental and theoretical viewpoint on the electronic carrier mobilities of typical hybrid organic-inorganic perovskites (HOIPs). While these mobilities are often…
