High-Resolution In-situ Synchrotron X-ray Studies of Inorganic Perovskite CsPbBr: New Symmetry Assignments and Structural Phase Transitions
S. Liu, A. R. DeFilippo, M. Balasubramanian +12
Perovskite photovoltaic ABX systems are being studied due to their high energy-conversion efficiencies with current emphasis placed on pure inorganic systems. In this work, syn…
Nature of the Structural Symmetries Associated with Hybrid Improper Ferroelectricity in Ca3X2O7
S. Liu, H. Zhang, S. Ghose +8
In hybrid improper ferroelectric systems, polarization arises from the onset of successive nonpolar lattice modes. In this work, measurements and modeling were performed to determi…
Ionic conductivity enhacements and low temperature synthesis of Li7La3Zr2O12 garnets by Bi aliovalent substitutions
Derek K. Schwanz, Andres Villa, Mahalingam Balasubramanian +2
We report on a novel approach to synthesize cubic-phase fast ionic conducting garnet-type solid state electrolytes based on Bi doped Li7La3Zr2O12 (LLZO). Bi aliovalent substitution…
Changes in charge density vs changes in formal oxidation states: The case of Sn halide perovskites and their ordered vacancy analogues
Gustavo M. Dalpian, Qihang Liu, Constantinos C. Stoumpos +4
Shifting the Fermi energy in solids by doping, defect formation or gating generally results in changes in the charge density distribution, which reflect the ability of the bonding…
