Self-flux-grown Ba4Fe4ClO9.5-x crystals exhibiting structures with tunable modulation

Arnaud Magrez, Alla Arakcheeva, Priya Ranjan Baral, Wen Hua Bi

The synthesis and X-ray structural study of the new family of compounds Ba4Fe4ClO9.5-x with tunable structural modulation are reported. The framework of the structure has the Ba2Fe4O9.5-x composition, with open hexagonal channels extending along the c-axis ...

Structure, heat capacity and Raman spectra of Ba2MgWO6 single crystals grown in BaCl2-MgCl2 flux

Henrik Moodysson Rønnow, Ivica Zivkovic, Richard Gaal, Wen Hua Bi, Jana Pásztorová

We present a new method of Ba2MgWO6 single crystal synthesis that allows to grow larger crystals using a BaCl2 and MgCl2 flux. Difficulties to grow single crystals of a size suitable for macroscopic material property measurements caused the majority of cha ...

Synthesis and crystal structure of Fe[SeO4]OH and prediction of polytypes in the extended R[MO4]Z family

Arnaud Magrez, Alla Arakcheeva, Wen Hua Bi, Benoît Guilhem Michel Binh Truc

Single crystals of Fe[SeO4]OH have been synthesized by hydrothermal treatment. The Fe[SeO4]OH structure was investigated using the superspace approach. It is shown that the structure belongs to a family of compounds including kieserite-like and pauflerite- ...

On the synergistic interplay between annealing temperature and time and additive concentration for efficient and stable FAPbI3 perovskite solar cells

Federico Turci, Arnaud Magrez, Andreas Schueler, Wen Hua Bi

Formamidinium-based lead triiodide perovskite (FAPI) is the workhorse candidate for highly efficient perovskite solar cells owing to its ideal bandgap and phase purity. An essential condition to that is the formation of a pure alpha-black phase, commonly t ...

High-Temperature Phase Transitions Preceding the Decomposition of Mixed Valence Aluminum Titanate Pseudobrookite

Henrik Moodysson Rønnow, Arnaud Magrez, Ivica Zivkovic, Yong Liu, Davor Tolj, Wen Hua Bi

Dark blue single crystals of Al1.753+Ti1.04+Ti0.253+O5 were grown with a novel synthesis method based on the reaction of a Ti3+/Ti4+-containing langbeinite melt and porous alpha-alumina crucible. The obtained needles crystallize in the pseudobrookite struc ...
