New Superconductors in the PtPbBi Structure Type
Lior Verbitsky, Amira Merino, Scott B. Lee +8
The quest for new superconductors is of both fundamental and technological importance. Recently, an artificial intelligence method correctly predicted PtPbBi to be a supercondu…
Bonding Interactions Can Drive Topological Phase Transitions in a Zintl Antiferromagnetic Insulator
Tanya Berry, Jaime M. Moya, David Smiadak +5
While 30% of materials are reported to be topological, topological insulators are rare. Magnetic topological insulators (MTI) are even harder to find. Identifying crystallogr…
Experimental Evidence for Defect Tolerance in Pb-Halide Perovskites
Naga Prathibha Jasti, Igal Levine, Yishay Feldman +3
The term defect tolerance (DT) is used often to rationalize the exceptional optoelectronic properties of Halide Perovskites (HaPs) and their devices. Even though DT lacked direct e…
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…
Effect of Halide Composition on the Photochemical Stability of Perovskite Photovoltaic Materials
Ravi K. Misra, Laura Ciammaruchi, Sigalit Aharon +4
Photochemical stability of encapsulated films of mixed halide perovskites with a range of MAPb(I1-xBrx)3 compositions (solid solutions) was investigated under accelerated stressing…
