Structural Chemistry of Layered Lead Halide Perovskites Containing Single Octahedral Layers

Philip Lightfoot, Jason A. McNulty

We present a comprehensive review of the structural chemistry of hybrid lead halides of stoichiometry APbX4, A2PbX4 or AAPbX4, where A and A are organic ammonium cations and X = Cl…

Complex Octahedral Tilt Phases in the Ferroelectric Perovskite System Li $_{x}$ Na $_{1 - x}$ NbO $_{3}$

Charlotte Dixon, Philip Lightfoot

High-temperature phase behavior in the system LixNa1-xNbO3 has been studied by using high-resolution powder neutron diffraction. Each of the three compositions studied in the Na-ri…

Ferrielectricity in an Organic Ferroelectric

James F. Scott, Finlay D. Morrison, Rebecca Clulow +7

We report ferrielectricity in a single-phase crystal, TSCC -- tris-sarcosine calcium chloride [(CH3NHCH2COOH)3CaCl2]. Ferrielectricity is well known in smectic liquid crystals but…

Structural phase transitions in the kagome lattice based materials Cs2-xRbxSnCu3F12 (x = 0, 0.5, 1.0, 1.5)

L. J. Downie, C. Black, E. I. Ardashnikova +6

The solid solution Cs2-xRbxSnCu3F12 (x = 0, 0.5, 1.0, 1.5) has been investigated crystallographically between 100 and 300 K using synchrotron X-ray powder diffraction and, in the c…
